摘要
We study mechanical properties of the surface layer and the electrochemical behavior of 40Kh steel subjected to preliminary vibration-centrifugal hardening treatment and determine the optimal conditions of treatment aimed at increasing the corrosion-electrochemical resistance and hardness of the hardened layer, namely, the weight of a tool should be equal to 45 or 75 N and the time of treatment to 20 or 36 min.
