【 摘 要 】

There has been studied the effect of heat input plasma hardening steels process 0.9 C-Cr-Si, 1 C and 1.7 C-Cr-Ni-Mo on the structure, the depth of hardening and the hardness of the local area. It is shown that a graded structure is formed along the depth of the zone with regularly changing dispersion and microhardness. There have been specified the dependences, allowing to operate the structural state and performance properties of the hardening zone, ensuring their optimum ratios for different wear conditions.
