Summary

This study is based on tests with hot isostatically pressed boron carbide in self-mated pin-on-disc and ring-on-ring contacts. The friction was continuously measured and the effects of sliding speed and heat treatment prior to testing were investigated. It was observed that heat generated reaction products have pronounced effects on the wear and frictional properties. Under suitable conditions smooth tribofilms develop, leading to a steady-state sliding mode. The conditions for these transitions are discussed.
