The influence of microstructure and hydrogen-containing environment on the intensity of cast iron and steel damage by sliding friction. Рart 1. The construction of a generalised model of surface layer friction of graphitized steel and cast-iron objects

Abstract

This paper analyses the mechanisms of abrasive wear based on research results and literary data. A generalised model describes the influence of microstructure, chemical composition and hydrogen-containing lubricant on the wear processes in the surface layers of cast irons and graphitized steels. Major factors affecting the intensity of wear are determined: pressure, speed of sliding, chemical composition and microstructure.
