Summary: Among different technologies of protective coverage`s in latter days the methods of gas-thermals spraying: gas flaming, plasmas, detonation and electro arc metallization got intensive development. In the basis of these methods, there is a single principle of formation of protective layer out of discrete particles of the material warmed up and speeded up by a gas steam. Spraying is the most convenient method of shaping of cover-age`s on the surfaces of details, which have different configuration. The main indexes of quality of coverage`s are hardness of cohesion and den-sity. At spraying they are insufficient. Density achieves 60% and hard-ness of cohesion 25–40 MPa. To increase quality of sprayed coverage`s namely hardens of cohesion and density, there are some directions: ap-plication of progressive technologies of preliminary preparation of the surface before spraying, processing of sprayed coverage.
