Wear rate calculations

Respected Sir
How can we calculate wear rate of different metals if we have wear, temperature, time, coefficient of friction, load, speed, frictional force as given parameters. and what should be method applied when we use Tribo tester for wear rate measurement.
waiting for your reply.

thank you

In a steady state, wear rate means amount of removed material in time. So, you only need to divide parameter 1 by parameter 3. Also, parameter 4 is obtained dividing parameter 7 by parameter 5. The analysis of a dynamic state takes in consideration changes in temperature, speed and other variables and their effects. Parameters are no longer constants but variables that need to be solved by other equations (mostly non-linear).
