Solution to the Diffusion Problem in the Thermocyclic Nitrocementation of Steel

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