Abstract
Results of studying the roughness of the working surface of a steel disk that operates in a pair with a copper-based metal-ceramic frictional layer under film lubrication are presented. The dependence of the root-mean-square roughness on the duration of operation in the steady wear mode is obtained. The microstructure of the 65G steel is identified at various values of the hardness and the dependence of the ultimate strength on the hardness is obtained. Recommendations on selecting rough surfaces and mechanical characteristics of the 65G steel for operation in a pair with the MK-5 metal-ceramic material are given.
