FIELD: iron and steel industry. SUBSTANCE: the invention presents the device for deposition of coatings on the internal surfaces of items, that may be used in engineering industry, aerospace engineering, in motor industry, energetics, building, oil-and-gas industry and other branches of economy for deposition of coatings on the internal surfaces of their products. The device contains a silo for a powder blend together with a feeder - batcher, a chamber of mixing, systems to feed a working gas into the chamber of mixing and into a feeder - batcher, linked to a source of the working gas. The device has a spraying head with a ring-type collector, a ring-type supersonic nozzle, a slewing device, that is made in the form of a ring and axisymmetric in respect to the central shaft of the spraying head. At that The slewing device is located in the body of the spraying head and is connected and conjugated with the ring-type supersonic nozzle and the shaft of the ring-type slewing device being a prolongation of the shaft of the ring-type supersonic nozzle is placed in relation to it at an angle of 90±5°, and the ring-type slewing device output cross-section faces the side opposite to the central shaft of the spraying head. EFFECT: the invention allows to increase productivity, to improve processibility and economy of the device operation. 1 dwg
