Possibility of obtaining favorable mechanical properties of materials for machine elements exposed to wearing and abrasion

Abstract

There are several options for increase resistance to abrasive wear of parts. Inserting the cocoon into the hole of machine part that is exposed to wearing, welding on worn parts, joining by explosion of different materials or obtaining the bi-nzetal and hardening of finished parts by explosion. The results of comparative studies of the properties of wear-resistant steels for the development of parts exposed to abrasion are presented in this paper. Experiment has included the analysis of the properties of explosion hardened steel 120Mn12, as well as the skills of bimetal (50Mn7 + S355). The results show that explosion processing in case of both variants of material lead to the improved resistance of the parts to abrasive wear
