Abstract

The results of experimental studies into the surface micromorphology, microstructure, and microhardness of deposited P2M8 high-speed steel subjected to gas-laser cutting are presented. It is demonstrated that, in the area of laser action, the volume wear rate of high-speed steel is three times lower as compared to standard strengthening by means of volume hardening and triple tempering.
