FIELD: iron and steel industry. SUBSTANCE: the invention presents the device for deposition of coatings on the external 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 external surfaces of their products. The device contains a silo for a powder blend together with a feeder - batcher, a chamber of mixing, a system to feed a working gas into the chamber of mixing, a system of the working gas feeding 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, a hollow channel for an item reception. The slewing device is made in the form of a ring and axisymmetric in respect to the central axis of the head. The slewing device is located in the body of the spraying head and is connected and conjugated with the ring-type supersonic nozzle. 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 central axis of the spraying head. EFFECT: the invention allows to increase productivity, to improve processibility and economy of the device operation. 1 dwg
