Abstract

The behavior of detonation and plasma coatings in conditions of dry friction against the OT-4 titanium alloy and 07Kh16N6 stainless steel has been studied. It is found that the detonation coatings have significantly better tribological properties than the plasma coatings. This is probably due to the presence of aluminum and titanium nitrides having high wear resistance in the detonation coatings. Oxidation of plasma and detonation coatings at a temperature of 900 °C in air has been examined. It is shown that the developed detonation and plasma coatings show greater oxidation resistance than uncoated VT-16 titanium alloy.
