EXPERIMENTAL INVESTIGATION OF TRIBOLOGY-RELATED SURFACE TOPOGRAPHY PARAMETERS AND HARDNESS OF 16MNCR5 CASE HARDENED STEEL

Abstract

Tribological properties are determinant in the functionality of contacting surfaces of machine elements. The wear resistance or load bearing capacity influence the lifetime of these parts. In this study tribology-related surface topography parameters (Ssk, Sbi) and the hardness of hard turned surfaces are analyzed after hardness and topography measurements. Correlation coefficients were calculated for their relationships. It was found that the cutting parameters affect the wear resistance and the hardness in the opposite direction.
