Effect of conditions of diamond grinding on tribological behavior of alumina-based ceramics

Resumo

Characteristic morphologies of the surface of oxide ceramics, which are produced by grinding, have been identified and a relationship between conditions of diamond grinding and these morphologies has been revealed using the developed method of study. It has been found that the type of the characteristic morphology of the surface of ground oxide-ceramic specimens has a strong effect on the tribological behavior of these specimens. The prime role of the grinding subsystem, which is a component of the manufacturing system for producing ceramic friction members, in the formation of the mode of wear at the run-in stage has been established.
