IMPROVING THE EFFICIENCY OF ELECTROCONTACT WELDING OF POWDER MATERIALS

Electrocontact welding of powder materials is one of the promising ways to restore machine parts. This paper presents the results of a study of the dependence of adhesion strength and wear resistance depending on the mode of electrocontact welding of a powder mixture containing crushed solid alloy waste. In this case, the coatings are obtained without melting solid powders, i.e. in the solid phase.
