One of the important tasks of modern materials science concerning technical issues is the need to ensure the surface properties of hardened products. An increase in the resource of machines and an increase in reliability are limited by the wear resistance of their components and assemblies: the less wear of the main rubbing pairs, the longer the service life [1]. For example, according to [1], a piston internal combustion engine accounts for 36-52% of the total number of machine failures. Modern technologies have a large number of hardening methods that can increase almost any characteristic of the structural strength of the material. Surface hardening of parts can be carried out in two ways - by changing (modifying) the state of the surface layer or by coating.
