FIELD: iron and steel industry. SUBSTANCE: the invention presents the device for deposition of a powder coating. It may be used in metallurgy, engineering industry, aerospace engineering, in motor industry, energetics, building, oil-and-gas industry and other branches of economy for deposition of coatings. The device contains a pistol type body with a supersonic nozzle, the powder and working gas feeding pipe stubs, a control button, a chamber of the powder and working gas mixing, that is linked with the powder and working gas feeding pipe stubs The supersonic nozzle is respectively connected and conjugated with the mixing chamber. The device allows quickly, operatively and qualitatively to deposit a powder coating on an item in the field, including extreme situations. EFFECT: the offered device allows operatively perform repair-and- recovery works in any situations, including the field works. 2 dwg |
