ball cratering

I would like to know web sites where to find information about micro abrasion wear test (ball cratering) and micro abrasion test apparatus. Test made in different materials.

Thank you

I do not know if you mean brinelling or
fretting?

This sounds related to the issue of lubricity of diesel fuels and similar. There are plenty of web sites that discuss the HFFR and BOCLE tests. There is a company in Chicago whose name escapes me for the moment, that makes the testing machines for these tests.
