    摘要: The invention relates to the technology of applying coatings to the surfaces of articles, and in particular, to gas-dynamic methods of applying coatings with the use of an inorganic powder, and it can be used in different branches of mechanical engineering. A compressed gas is delivered to the heater (1) to be heated to the required temperature that keeps the particles from sticking to the nozzle walls. The heated gas enters the supersonic nozzle (2) wherein it sequentially passes through a converging portion, the throat (3) and a diverging portion of the nozzle and acpelerates up to supersonic velocity. The powders to be sprayed are introduced into said supersonic gas flow through powder injection components (5). The powder particles are accelerated by a high-velocity gas flow in the acceleration portion (7) of the nozzle and then they are directed to the substrate surface. The gist of the invention is the disclosure of the parameters of a nozzle portion, positioned downstream of the powder injection point and intended for the acceleration of the powder, providing the increase of sprayed powder deposition efficiency and the retention of the possibility to use an elevated temperature of the compressed gas and to use the powders having hard particles.
