Priazovsky State Technical University, Mariupol, UkraineAbstract
Causes of defects formed in surface layers of tool steels as a result of treatment of workpieces with high power density heat sources are considered. Peculiarities of formation of defects in laser and plasma treatment are noted. Methods for reducing the probability of formation of defects are suggested
Keywords: heat hardening, heat sources, laser and electron beam, plasma jet, phase and structural transformations, defects
