Abstract
The article deals with the development of ion-plasma coating systems based on multilayer heterogeneous structures of the type (Me1)N/(Me2)N, (Me1–Me2)N/(Me3)N, (Me1–Me2–Me3)N/(Me4)N, where Me: Ti, Al, Cr, Mo. Tests for heat resistance and wear resistance, gas-abrasive resistance, metallographic and x-ray structural studies were carried out. It is shown that the ion-plasma coating (Ti–Al–Cr)N/CrN can be used to increase the heat resistance, wear resistance (including abrasive) of steel and titanium intermetallic parts of aircraft gas turbine engines operating in the temperature range up to 800 °C.
