Abstract
Currently, methods of thermal spraying are widely used to restore and harden various worn parts of machines. In most cases, metal and composite wires are used as materials for gas-thermal coating applying methods. As a rule, metal coatings applied by thermal spraying have lower strength characteristics than cast materials. An important factor characterizing the possibility of using metal coatings in various industries is their density and adhesion strength of coatings with the base metal. In this paper, the structure and density of coatings, as well as the adhesion strength of coatings made of steel and titanium wires deposited by hypersonic metallization were studied.
