The influence of surface topography on selected tribological properties of hardened 100Cr6 steel after turning

Results of surface topography analysis and selected tribological properties of samples of 100Cr6 bearing steel after turning with variable feed are presented. The hardness of samples after heat treatment carried out in a vacuum furnace (including quenching and double tempering) was 60 ±1 HRC. The influence of turning feed on surface topography after machining as well as selected tribological properties were determined. Depending on the surface topography of samples, differences between values of friction coefficients and wear rates were about 25%. Moreover, along with the surface roughness changing, different nature of wear was found.
