It is shown that cyclic heating and cooling considerably accelerate the kinetics of chemical thermal processing of steels. The author studies the laws of formation of the strengthened layers at thermocyclic nitrocementation of steel 20 Kh. Production tests of machine parts after chemical thermal and chemical-thermocyclic processings were performed. The structure, phase composition and intensity of wear process of a blanket depending on a number of cycles are investigated.
