Abstract
The possible technologies of formation of nanostructured surface layers: a method of thermal mass transfer in a high temperature gradient; the combined method, comprising plasma nitriding a cathode in a low pressure and deposition of titanium nitride in a single process cycle; combined method comprising an ionic nitriding and high frequency deposition of chromium carbide by pyrolysis of organic chromium compounds in a glow discharge plasma are considered. The possibility of formation of nanostructured layers is shown. Examples of the practical use of these technologies are given. The tests found that the use of the combined coating nitriding + TiN increases cyclic durability of machinery parts in contact loading conditions and corrosive environments on the two orders, providing a specified level of reliability and combined nitriding + CrC coating on steel С1050 allowed to reach values of the fatigue limit under Impact NaCl 400 MPa.
