Wear resistance of composite plasma coatings with graphite

Аннотация

The wear-resistant composite solid lubricant coatings formed by atmospherec plasma spraying method of cladding Ni[Cg] powder in relation to the extreme working conditions of friction units of aircraft engines and power plants have been investigated. Examples of studies of technological processes of the plasma spraying of protective coatings on elements of liquid-propellant rocket and gas turbine engines have been given, and the possibilities of sealing technologies to increase their service life have been shown. The evaluation of efficiency of coatings obtained by plasma spraying from mechanical mixtures of powders based on Ni[Cg] in relation to power plants of vehicles based on freepiston engines.
