Abstract

The paper presents results of research on a method of determining a geometric condition of a sintered surface using an instrumental digital microscope. The results of experimental studies of effects of laser irradiation technological modes on roughness of the cobalt chrome molybdenum powder DSK-F75 sintered layer are presented. Differentiation of modes of product surface and its internal volume formation into rough, semi-finishing and finishing are proposed.
