For more information
A suspension is used to limit the vibration induced by the sample during testing. There are several variations of suspensions depending on the maximum load it can be effective on. .
It is recommended to select a suspension system with the closest higher load rating to the expected load.
For example, if you realize a test at 150N, you would need to use the 200N suspension. By doing so, you will mitigate the vibrations the most.

Install the Linear Reciprocating Drive
Technical specification:
Proper alignment of the sample on the reciprocating holder helps maintain its rated life.
The load factor applied to any reciprocating system is still the main factor determining its rated life.
The reciprocating mechanism can withstand high loads when used within its designed operating conditions. However, the general mechanical principle described below cannot be avoided.
rated life: the total travel distance that 90% of linear guides can reach
X₀ → Maximum X Differential Position
The maximum offset of the load along the X-axis relative to the center of the drive.
This value accounts for the total stroke displacement.
This value accounts for the total stroke displacement.
Y₀ → Maximum Y Differential Position
The maximum offset of the load along the Y-axis relative to the center of the drive.
Load
It depends on the position of the applied force. Refer to the following document for guidance on determining the maximum allowable load per test.
For example, if the X.Position is 0 mm and the stroke is 10 mm, then X₀ = 5 mm.
This information and the maintenance assessment should be taken into consideration during high-load testing procedures.
- Adjustable Stroke length: 0.1-30 mm
- Frequency: 0.1-80 Hz ( 80 Hz @ 1 mm, 60 Hz @ 2 mm, 20 Hz @ 25 mm).
- The maximum allowable frequency is determined by the current stroke length. The respective limits must not be exceeded.
- Some reciprocating drives are not fully covered by this specification, e.g., SPN04316 – up to 15 Hz. Please refer to your packaging list if unsure or unaware of this information, or contact Rtec Support for assistance.
- (Option) LVDT Linear Encoder Range: 25.4 mm (+/- 12.7 mm); Resolution: 1 um
When using the reciprocating system in combination with the LVDT, the stroke length limitation becomes 25.4 mm. The stroke length cannot be accurately measured or guaranteed beyond this value.
- Position the reciprocating drive on the base.
Ensure that the black connector underneath the module is properly aligns and connects with the green connector on the base.
- Use two 8-32 screws (BM310280-12) to secure the reciprocating drive.
Adjusting the Stroke Length
Please remember that the maximum frequency varies according to the stroke length. ( 80 Hz @ 1 mm, 60 Hz @ 2 mm, 20 Hz @ 25 mm).
When using the reciprocating system in combination with the LVDT, the stroke length limitation becomes 25.4 mm. The stroke length cannot be accurately measured or guaranteed beyond this value.
- On the MFT Software , disable the drive by clicking on the ON button.
Click on “ON” to switch off the motion. The module must be “OFF”.
The drive must be disabled in order to freely move the reciprocating and get access to the adjustment screws.
The drive must be disabled in order to freely move the reciprocating and get access to the adjustment screws.

Part 4: Alert, Machine manual control and Test control
Alarm part
In this window, all the current alarms impacting the tester are shown.
Machine manual control
Machine manual control allows the user to manually control the displacement of the X, Y, Z stage and the module installed.
For X, Y and Z, the 2 first buttons move the axis in the direction of the button whenever pressed. The last button (“Distance”) allows the user to move the axis by a specific distance in a positive or negative direction.
By dragging the slider on the right of the window, you can uncover other parameters.
- Vel: It is the displacement value (in mm/s) of the X, Y platform when moving the X, Y platform using the machine manual control upper window.
- Move Abs XY: This part will be available if the tester is homed. It allows the user to move to a specific absolute position of the X, Y platform. This position is defined based on the home position.
The button on the left refreshes the current XY position.
You can enter the X and Y absolute position in the free space and then press ”XY Move” to move to this absolute position.
In the current version, the move Abs XY may have some problems, it is recommended to use the “Distance” of manual control explained previously.
- Teach Offset: This parameter is used to teach the offset between the testing and imaging position of the tester. This is the part where you can do the inline imaging calibration. It will be introduced further in Part 2.2.2.4.1.
- Move Offset: This parameter is used to automatically move between the testing and imaging position.
- TEST => IMG: The platform goes from the test position (where the sample is located below the load cell) to the imaging position (where the sample is located below the imaging head)
- IMG => TEST: The platform goes from the imaging position (where the sample is located below the imaging head) to the test position (where the sample is located below the load cell).
Make sure that you are using the right move offset type. If you are in the test position and use “IMG => TEST”, the platform will go in the wrong direction. It will be stopped and the initial position will be lost.
The “Move Offset” needs to be calibrated in order to efficiently move between the testing and imaging positions. The calibration will be introduced further in Part 2.2.2.4.1.
On the right side of the manual control window should be the manual module control. This window allows the user to manually use the module installed.
By clicking on the “ON” button, you can turn the motor off.
Next to it should be possible to modify an intrinsic parameter of the module: frequency (Hz), speed (RPM) etc…
The two buttons at the right start (Left one) and stop (Right one) the manual movement of the module.
The “Distance” button on the far right allows you to set a number of rotations / cycles.
Test Control Window
On the test control window, you can control the homing (Left), Start (Middle) and Stop (Right) of the recipe.
Add Steps
Reciprocating using the X Axis Table
Add a Standard Step
- Click the drop-down menu and select Standard.
- Click ADD a new step.
- Define the duration of the step in the DURATION Section.
- Define a constant or linear force within the range of the sensors and suspension.
- Press ENTER.
Remember to define values below the limits of your load cell and suspension.
(Refer to the load cell manual, suspension section for help)
Help
Cannot define a force within the sensor range → verify the selected sensors range in selecting the components.
For more information
Principle of the STANDARD Step:
A standard step can combine multiple axis and module activations, such as applying a force (Z stage), enabling motion (Drive function), and heating the sample (Temperature function for chambers).
During this combinated step, the force is first applied and stabilized. Then, if a heating chamber is used, the defined temperature is reached. Finally, the drive type of motion drive is activated and the duration starts.(unless the engage parameters are modified).
Part 1: Duration
Duration of the step
In this window you can control the duration of the step.
The highlighted button allows the user to automatically calculate the duration of the step if the parameters selected offers to do so with a defined duration of a single repetition and certain number of repetitions (Slide for example)
By default, the logging and time duration start after the force is reached. (see Waiting for force/temperature to settle further)
Part 2: Reset
In this window you can reset the value of Fx at the beginning of the step. If it is unchecked, the Fx value will not be subjected to any reset.
This option is necessary to be pressed only when there is an offset of the Fx value at the beginning of the test (1D+1D arm), it will create issues in most cases when using a 2D Load Cell.
Part 3: Data Logging
Checking “Log during this step” will record the test data during the step. If it remains unchecked, no data will be logged for this step.
In case the user wants to divide the data logging into smaller periods, he can modify the values of “Log Period” and “Log Interval”.
- Log period (seconds): The duration of the log period.
- Log Interval (seconds): The duration of the interval between 2 log periods.
Part 4: Force
The Z-Axis will reach out for a contact when applying a constant force of 0 N as opposed to the undefined option.
Each force are defined for each step, this aspect must be taken in consideration, meaning that the same force must be defined each step to keep applying the desired force throughout the run-test.

X axis motion
In this parameter, the user can command an action of the X axis for the step.
- Idle: X axis does not move the during the step.
- Cycle: Triangular motion along the X axis for the entered distance and number of cycles.
- Distance: Amplitude of the X-axis displacement.
- Velocity (rpm): Final velocity of displacement after the acceleration phase.
- Acceleration (s): Acceleration phase duration.
The previous position of the X table is used as the origin. The distance setting will thus be the distance from the previous X position.
For example, if the X position is 0 and the Amplitude is set to -2mm, the axis will create a triangular movement between X=[0;-2mm]
- Slide: Moves the X axis for the entered distance relative to the previous position (positive and negative as shown on the X, Y platform).

ex: 5 mm
For more information
Most Rtec-Instruments load cells are designed to measure friction along the X-axis (Fx).
Because of this, it’s important to always set Y to a nominal value and X = 0. This ensures that all friction forces appear only along the X-axis, where the sensor can detect them.
If you adjust the radius along X, the friction force will shift to the Y direction (Fy). In that case, the load cell will not be able to measure it correctly, and it could even cause damage to the sensor.
Add a Standard Step
- Click the drop-down menu and select Standard.
- Click ADD a new step.

Principle of the STANDARD Step:
A standard step can combine multiple axis and module activations, such as applying a force (Z stage), enabling motion (Drive function), and heating the sample (Temperature function for chambers).
During this combinated step, the force is first applied and stabilized. Then, if a heating chamber is used, the defined temperature is reached. Finally, the drive type of motion drive is activated and the duration starts.(unless the engage parameters are modified).
Part 1: Duration
Duration of the step
In this window you can control the duration of the step.
The highlighted button allows the user to automatically calculate the duration of the step if the parameters selected offers to do so with a defined duration of a single repetition and certain number of repetitions (Slide for example)
By default, the logging and time duration start after the force is reached. (see Waiting for force/temperature to settle further)
Part 2: Reset
In this window you can reset the value of Fx at the beginning of the step. If it is unchecked, the Fx value will not be subjected to any reset.
This option is necessary to be pressed only when there is an offset of the Fx value at the beginning of the test (1D+1D arm), it will create issues in most cases when using a 2D Load Cell.
Part 3: Data Logging
Checking “Log during this step” will record the test data during the step. If it remains unchecked, no data will be logged for this step.
In case the user wants to divide the data logging into smaller periods, he can modify the values of “Log Period” and “Log Interval”.
- Log period (seconds): The duration of the log period.
- Log Interval (seconds): The duration of the interval between 2 log periods.
Part 4: Force
The Z-Axis will reach out for a contact when applying a constant force of 0 N as opposed to the undefined option.
Each force are defined for each step, this aspect must be taken in consideration, meaning that the same force must be defined each step to keep applying the desired force throughout the run-test.

BOR Effective Radius Calculations
For Block On Ring test, the Friction Coefficient (COF-Torque) is calculated using the effective radius entered in the “Radius” field of the previous window.
The effective radius of the block on ring depends on the amount of contact areas where the friction occurs:
- Ring test: Only one single contact point at the radius of the ring.
- “Radius” = Radius of the ring (mm).
- Bearing test: Two contact points: One between the balls and the inner ring and a second one between the balls and the outer ring.
- “Radius” = Effective radius of the 2 contact areas (mm).
The effective radius can be estimated as follows:
Ff,i being the friction force at a specific contact radius.

The standard step duration and start enable after the force is reached.
The Z Stage goes back to its initial position (before pressing start)
Tracking : Adjusting the reaction time
Any Standard Step → Tracking options
The tracking options are individuals for each standart steps defined.
- Low: Reduces the Fz reaction time and adjustment intensity. Only to be used if the standard option is adjusting too strongly to a slow Fz evolution (Tests with fast and high Z displacement).
- Standard: To be used in most cases.
We highly recommend to use the Standard tracking. However, if the tracking of the force is not satisfactory, you can try other possibilities or contact Rtec customer service if you cannot obtain a satisfactory tracking of the force
- High: Increases the Fz reaction time and adjustment intensity. Only to be used if the standard option is adjusting too slowly to a rapid Fz evolution (Tests with fast and high Z displacement).
Disengage at test end
the Z drive automatically move back to the Z starting position
- It can be higher or lower than final position)
- Unchecked, the Z drive will stay at the final position when the test ends.
Engage Velocity
This option allows the user to set the approaching speed of the Z drive towards the lower sample.
- Low: Recommended for very low force and sensitive application. The touch force will not reach high values.
- Medium: Recommended for most cases, the velocity will be faster than Low engage velocity but the touch force will still be relatively low.
- High: High engage speed to find the touch point rapidly. Brings higher touch force. for relative high load application (>500N), this engage speed is useful to quickly reach the sample and desired force. However it is not recommended for lower load application because of the significant overshoot provoked.
It is recommended to adapt the engage velocity to every situation and to always perform an initial coarse approach using the jogbox.
Environmental Settings (For chamber module)
- Wait for the temperature to settle: If checked, the step duration time will start when the desired temperature is reached. Otherwise, the load and drive will reach their defined value immediately.
- Maintain environment: If checked, the desired temperature in a step shall be maintained throughout the recipe steps. This temperature matches the last one defined in the recipe.

Please Read all the information below before operating:
- As all the motions are executed in order: Velocity must be placed before an offset or position (X,Y,Z.Offset or X,Y,Z.Position) to operate with the defined speed. (otherwise, the default velocity will be applied to the displacement).
- If the starting position is lower than the previous position of the reposition, the reposition step will still go down to the original recipe position.
- For additional reposition step placed during the recipe, please unmark “disengage Z before reposition”.
The reposition step allows for the movement and control of different components without any testing. This step is typically used to position samples, move to a new location, reset sensors…
For more information
Part 1: General functions
- “Log during this step”: If checked, logs the data of the reposition parts.
- “Disengage Z (Before Reposition)”: Disengages Z to the starting position of the recipe to avoid any contact with the sample during the reposition step.
- Remove item: Remove one of the items in the reposition step
- Add item: Add an item at the end of the reposition step
- Insert item: Add an item before the one selected in the reposition step
Part 2: Reposition commands
There are several types of reposition commands depending on the type of modules installed:
- Sensors Reset: Automatically biases the value read by the sensor. The value read at this step will become the new 0.00.
- Sensor.Reset Fz: Biases the normal force sensor reading.
- Sensor.Reset Fx / Fx-Piezo: Biases the lateral force sensor reading.
- Sensor.Reset TS / Tz): Biases the torque sensor reading.

Sensors to bias
Sensors not to bias
- X, Y, Z, ZWLI axes:
- (X/Y/Z).Position (mm): Positions the drive to the nominal value.
- (X/Y/Z/ZWLI).Offset (mm): Positions the drive to a value that is an offset from the previous position. (ZWLI corresponds to Z2, the Imaging axis).
- For example, if the previous X.Position is 1mm and X.Offset is -5, the new position will be -4.
- (X/Y/Z/ZWLI).Velocity (mm): Sets the velocity of the axis. (ZWLI corresponds to Z2, the Imaging axis).
- Z.Reset Depth: Biases the value of the Z.Depth parameter which can be selected in “Data Logging”.
- Drives:
- R/T.Move Angle: Move to a specific angle of the shaft (See Help)
- R/T.Reset Position: Sets the current shaft position as the new 0.00 angle. (Bias the angle value)
- T.Rotate: Maintains the rotation of the motor during the reposition step. (See Help)
- T.Home: Goes to the home position of the scratch table metallic plate.
- T.GoToTest: Moves the scratch table to a position where the CAP sensor detects the surface.
The angle of the shaft is not a nominal value of the motor and will change after an instrument restart.

Move to Angle is not working
You need to manually activate the drive and rotate it once for the motor to be able to receive the move to angle order (by using the rotation manual control for example)
The motion is not maintained during the reposition step
If you would like to maintain the motor motion during a reposition step (which was set prior to that reposition step), you will need to insert a custom step with the same motion parameters as the ones at the end of the standard step (Velocity, Direction…).

Machine manual control
Machine manual control allows the user to manually control the displacement of the X, Y, Z stage and the module installed.
For X, Y and Z, the 2 first buttons move the axis in the direction of the button whenever pressed. The last button (“Distance”) allows the user to move the axis by a specific distance in a positive or negative direction.
By dragging the slider on the right of the window, you can uncover other parameters.
- Vel: It is the displacement value (in mm/s) of the X, Y platform when moving the X, Y platform using the machine manual control upper window.
- Move Abs XY: This part will be available if the tester is homed. It allows the user to move to a specific absolute position of the X, Y platform. This position is defined based on the home position.
The button on the left refreshes the current XY position.
You can enter the X and Y absolute position in the free space and then press ”XY Move” to move to this absolute position.
In the current version, the move Abs XY may have some problems, it is recommended to use the “Distance” of manual control explained previously.
- Teach Offset: This parameter is used to teach the offset between the testing and imaging position of the tester. This is the part where you can do the inline imaging calibration. It will be introduced further in Part 2.2.2.4.1.
- Move Offset: This parameter is used to automatically move between the testing and imaging position.
- TEST => IMG: The platform goes from the test position (where the sample is located below the load cell) to the imaging position (where the sample is located below the imaging head)
- IMG => TEST: The platform goes from the imaging position (where the sample is located below the imaging head) to the test position (where the sample is located below the load cell).
Make sure that you are using the right move offset type. If you are in the test position and use “IMG => TEST”, the platform will go in the wrong direction. It will be stopped and the initial position will be lost.
The “Move Offset” needs to be calibrated in order to efficiently move between the testing and imaging positions. The calibration will be introduced further in Part 2.2.2.4.1.
On the right side of the manual control window should be the manual module control. This window allows the user to manually use the module installed.
By clicking on the “ON” button, you can turn the motor off.
Next to it should be possible to modify an intrinsic parameter of the module: frequency (Hz), speed (RPM) etc…
The two buttons at the right start (Left one) and stop (Right one) the manual movement of the module.
The “Distance” button on the far right allows you to set a number of rotations / cycles.

Rotary Recipe
Simple rotary test

- Sensor.Reset Fz: 1
- Sensor.Reset Fx: 1
- Y.Position: Your test radius value
- X.Position: 0
- Disengage Z: ✅
- (Optional) rename it : Reset Sensor & Position
X axis Position must be at 0 for rotary tests
Most Rtec-Instruments load cells are designed to measure friction along the X-axis (Fx).
Because of this, it’s important to always set Y to a nominal value and X = 0. This ensures that all friction forces appear only along the X-axis, where the sensor can detect them.
If you adjust the radius along X, the friction force will shift to the Y direction (Fy). In that case, the load cell will not be able to measure it correctly, and it could even cause damage to the sensor.

Rtec Instruments ASTM G99 Test Protocol
This procedure is based on the ASTM G99 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus.
The full standard is available from ASTM International (www.astm.org). This document is not a substitute for the official ASTM G99 standard.
The full standard is available from ASTM International (www.astm.org). This document is not a substitute for the official ASTM G99 standard.
Summary of Standard
This test method covers a laboratory procedure for determining the wear of materials during sliding using a pin-on-disk apparatus.
Materials are tested in pairs under nominally non-abrasive conditions. For the pin-on-disk wear test, two specimens are required.
One, a pin or ball that is positioned perpendicular to the other, usually a flat circular disk. The tester causes stationary pin/ball to press against the rotating disk at a known force and speed. During the test COF, friction, wear etc. parameters are measured and reported.

This standard is applicable to metallic samples, non metallic, polymers, ceramics, composite materials etc.
Procedure
Check the hardware installation
After having followed the basic step-by-step software:
- The upper load cell and lower rotary modules are properly installed following their respective steps.
- The additional thermocouple must be connected in place at a location close to the wearing contact as indicated in ASTM G99. It is recommended to attach it to close to the ball as it is stationary during the test.
- The software configuration have been followed, therefore, the temperature component is selected.

Only X-axis tests can be performed on most load cells.
Most Rtec-Instruments load cells are designed to measure friction along the X-axis (Fx).
Because of this, it’s important to always realize a X-axis reciprocating motion. This ensures that all friction forces appear only along the X-axis, where the sensor can detect them.
If you active the Y motion, the friction force will shift to the Y direction (Fy). In that case, the load cell will not be able to measure it correctly, and it could even cause damage to the sensor.

TriboCorosion Test
Tribocorrosion evaluates how mechanical wear and electrochemical corrosion interact when a material is exposed to both sliding contact and a corrosive medium.
It simulates real service conditions to assess film stability, material loss, and wear–corrosion synergy.
Test Types:
- Standard Tribocorrosion Test (OCP): No applied potential — measures natural potential (E(t)) to study film breakdown and repassivation.
- Anodic Tribocorrosion Test: Constant applied potential — monitors current (I(t)) to assess wear–corrosion under controlled anodic protection conditions.

- Focus on kinetics (how quickly the surface film breaks down and repassivates):
- Drive ON: 60–120 s
- Drive OFF: 180–300 s.
- Focus on steady wear (long-term equilibrium behavior under sustained mechanical action):
- Drive ON: 180–300 s
- Drive OFF: 90–120 s.
T = Total material volume lost under mechanical and corrosion influence

Determine Reciprocating Parameters:
Define the reciprocating motion parameters (stroke length, frequency) that provide consistent mechanical contact and realistic wear conditions for your specific tribo-corrosion testing.
Parameter | Symbol | Typical Range |
Stroke length | L | 1–5 mm |
Frequency | f | 0.5–5 Hz |
Normal load | Fₙ | Material-dependent |
Repassivation kinetics (τ) — how to compute:
Extract the repassivation time constant τ by fitting the weVoltage curve using:
E(t): Potential at time t after sliding stops.
Emin: The lowest potential right when sliding stops (most active state).
Emin: The lowest potential right when sliding stops (most active state).
E∞: The final potential after full recovery (steady passive state).

- Determine C0 by using the following formula:
Where:
t: Time of exposure (s): Total sliding duration (Drive ON periods) for the tribo-corrosion (Recipe 1 & 2) tests.
n: Valence number: Number of electrons exchanged per atom during oxidation.
F: Faraday constant (96485 C.mol-1)
ρ: Density of the material (g.cm-3)
Synergy Calculation
The total material loss (T) from the tribocorrosion test, the pure mechanical wear (W0) from dry or inert testing, and the pure corrosion loss (C0) from Tafel analysis are used to calculate the synergy term (S), which quantifies the interaction between wear and corrosion.
S represents the synergistic material loss arising from the interaction between mechanical wear and corrosion processes.
The result is specific to the OCP tribocorrosion test.
Anodic Tribocorrosion Test
This test only applies to samples which have an anodic protection area (passive materials).
Help
How to Check if a Material Has an Anodic Protection Area:
Use a short potentiodynamic polarization scan of the sample in the intended electrolyte:
- Start: at OCP, sweep anodically (e.g., OCP – 0.1 V → OCP + 1.0 V vs. reference).
- Look for three regions:
- Active region: current increases with potential.
- Passive region: current drops sharply to a low, steady value ipass over a broad potential range.
- Transpassive/pitting region: current rises again at Epit.
- If a stable passive plateau exists between the active and transpassive regions, the material has an anodic protection (passive) zone.
- The potentiostatic setpoint for the anodic test must lie inside that passive plateau, typically OCP + 100–300 mV, and below Epit.
Why active samples cannot be used:
Only materials with a stable passive film can sustain controlled anodic polarization without undergoing continuous dissolution.
If the sample is active (no passive window), applying OCP + mV will drive aggressive corrosion instead of stable tribocorrosion.
Example of active and passive materials:
Category | Typical Passive | Typically Active |
Steels | Stainless steels (≥10.5 % Cr) | Carbon steels, low-alloy steels |
Ni / Co Alloys | Ni-Cr alloys, Co-Cr-Mo, Inconel | Pure Ni (in Cl⁻) if film unstable |
Light Metals | Al, Ti, Zr, Ta, Nb (strong oxide formers) | Mg, Zn, their alloys |
Others | Passivated Cu, bronzes (mildly), Cr | Cast irons, active Cu in chloride media |

- Run the test
- Plot:
Based on that curve, find a suitable point within the passive region (Oxidation) (OCP+ΔE where ΔE=[100;300]mV). It will be used for the anodic protection recipe.
OCP + 150mV typically works well for passive regime determination.

- Open Rtec Insight and compare the weVoltage [E(t)] between the sliding and idle steps to determine:
- Stability of cathodic protection during sliding (verify current remains constant and small).
- Absence of hydrogen evolution: confirm no large current spikes or oscillations.
If current fluctuates strongly or hydrogen bubbles appear, reduce the applied cathodic offset (use OCP − 300 mV or OCP − 250 mV).
- Take a profilometer image of the wear mark to determine W0.
W0: Total material volume lost without corrosion influence.
Help
Determine Steps duration:
- Focus on kinetics (how quickly the surface film breaks down and repassivates):
- Drive ON 60–120 s, Drive OFF 180–300 s.
- Focus on steady wear (long-term equilibrium behavior under sustained mechanical action):
- Drive ON 180–300 s, Drive OFF 90–120 s.
Anodic Tribocorrosion test
Evaluates tribocorrosion behavior under controlled anodic polarization within the passive region.

Repassivation kinetics (τ) — how to compute:
Extract the repassivation time constant τ by fitting the weVoltage curve using:
E(t): Potential at time t after sliding stops.
Emin: The lowest potential right when sliding stops (most active state).
Emin: The lowest potential right when sliding stops (most active state).
E∞: The final potential after full recovery (steady passive state).
t: Time after sliding stops.
τ: Time constant (s); after t=τ, recovery ≈63% complete
Tafel Plot - W0 Calculation
Using the log(I)=f(E) plot obtained previously, you can determine C0 by using the following formula:
Where:
t: Time of exposure (s): Total sliding duration (Drive ON periods) for the tribo-corrosion (Recipe 1 & 2) tests.
n: Valence number: Number of electrons exchanged per atom during oxidation.
F: Faraday constant (96485 C.mol-1)
ρ: Density of the material (g.cm-3)
Synergy Calculation
The total material loss (T) from the tribocorrosion test, the pure mechanical wear (W0) from dry or inert testing, and the pure corrosion loss (C0) from Tafel analysis are used to calculate the synergy term (S), which quantifies the interaction between wear and corrosion.
S represents the synergistic material loss arising from the interaction between mechanical wear and corrosion processes.
The result is specific to the anodic tribocorrosion test.
