Abstract
A method of nanostructural modification of the surface of metal samples previously subjected to heat treatment using femtosecond laser radiation is considered. The results of experiments on the study of the process and determination of technological modes of laser microtreatment (surface peening and laser grinding) are presented. An increase in surface microhardness for hardened workpieces made of tool steels and a subsequent decrease in roughness without loss of hardness are shown.
