Archard Wear coefficient

[polyt]

I need some values of the Archard coefficient for steel-steel contact in fonction of pressure and slip velocities.
In fact I have to study the wheel-rail contact.
Where can I find that kind of values.?

We have published widely on this subject (if you are still interested). Using twin disk testing we have gathered some data on wear coefficients for wheel/rail materials (not quite Archard coefficients but essentially amount to the same thing). Take a look at
