The indicators of contact endurance during vacuum carburizing and ion nitriding of high-quality VKS-7 and VKS-10 steels are considered. Information about the modes of chemical-thermal treatment is given and the technological process of machining is considered. Statistical data on the destruction of samples at given stresses are presented. The graphical analysis of the obtained values after testing was carried out and the optimal variant of chemical-thermal treatment was selected for each of the given steels, which gives the best performance in terms of mechanical characteristics and operational requirements.
