Metallographic studies of hardened zones of steel 40Kh were carried out. Regression equations were obtained and the surface depth and width of the hardened zones as functions of the beam scanning speed and radiation power at different beam defocusing were plotted with the help of a full factorial experiment. Comparative wear tests showed that, with increasing hardening area to 100% of the friction surface, the wear resistance increases by a factor of 4.47 as compared to normalized steel.
