Abstract

Increased wear resistance of machine parts continues to be one of the most urgent problems of modern machine building. Despite the intensive development of different ways of protective hardening treatment, the technologies based on thermochemical methods are quite popular and widely used to improve the performance characteristics of parts. Nitriding of the surface layer of parts as a way of improving their reliability has a considerable history of development and improvement and continues to develop relying on scientific advances in the field of high energies. However, tightened operating conditions of modern machines and equipment require creating new nitriding technologies that can provide a complex of properties of parts surface layer and therefore specified performance characteristics.
