Can the wear rate be estimated in terms of width reduction of that particular asperity. Example, can the reduction in width of drill bit button as it drill be classified as the wear rate ? Only the width reduction (mm). Thank you.
Yes. If you know the original geometry of the button and reduction in the width or height, then you can calculate the volume of the drill bit button which is worn out. Thus, you can calculate the wear rate for your application.
Can I ask you? I used the Arcard formula to calculate tire wear. If I want to calculate the percentage of tire wear, how will it be calculated? I'm thinking that dividing the wear volume by the all tire volume gives the percentage volume of wear.
You are right in calculating % wear. However, the best way of reporting wear would be "wear coefficient", as given in the Archard's law. Or, you could express wear as specific wear rate (mm^3/N-m).

Is there any free simulation software to calculate amount of material removed by wear under dry and lubricated sliding pairs?
Simulation of tribological process is very difficult due to many factors that affect friction and wear.
