The parameters of contact fatigue strength during vacuum carburization and ion nitriding of high quality steel ( HQS ) HQS-7 and HQS -10 are considered. Information about the modes of chemical and heat treatment is given and the technological process of hardening for HQS -7 and HQS -10 steels is considered. The characteristics of the contact fatigue strength of steels in the statistical aspect at different levels of contact stresses are obtained. A graphical analysis of the obtained values after testing was carried out, the optimal stresses for research were determined and the optimal version of chemical heat treatment was selected, which determines the best indicators for mechanical characteristics and operational requirements.
