Abstract

The influence of nanocrystalline structure formed by mechanical pulse treatment on contact fatigue of 65G steel was researched. It was shown that contact fatigue of the steel depends on parameters of treatment. Using the optimal parameters of treatment which ensure the maximal depth and microhardness of hardened surface layer, the contact fatigue of 65G steel increases in 1,4‑2,1 times compared with grinded specimens after quenching and low-temperature tempering.
