Abstract

The method of nanostructural modification of the surface of metal specimens preliminarily subjected to heat treatment by femtosecond laser radiation is considered. The results of experiments on investigation of the process and determining the technological regimes of the micro-scale treatment of specimens—surface hardening and laser grinding—are presented. An increase in the surface microhardness for hardened blanks of tool steels and a subsequent reduction of the roughness without loss of hardness are demonstrated.
