Investigation of abrasive wear after combined hardening by deformation wave and heat treatment

Abstract

The article describes a new method of combined hardening, using sequential processing by wave strain hardening (WSH) and heat treatment (HT). The possibility of increasing the hardness of the surface layer by the proposed method while maintaining the impact strength of the material at an acceptable level has been established using the example of steel 65G. The results of studies of operational properties (abrasive wear resistance) of samples after hardening by combined technology are presented. Technological recommendations are given for the choice of hardening modes, which makes it possible to increase the mechanical properties of the material and reduce the abrasive wear of samples made of 65G steel. The proposed technology can be applied to the processing of heavily loaded machine parts operating in aggressive conditions and significant shock loads.
