The apparatus is comprised of a compressed air source which is connected by a gas conduit to a heating unit whose outlet is connected to a supersonic nozzle inlet in which a supersonic portion is connected by a conduit to a powder feeder. Compressed air of pressure Po from the compressed air source by the gas conduit is delivered to the heating unit to be heated to the required temperature. The heated air enters the supersonic nozzle in which it is accelerated to a speed of several hundred meters per second. The powdered material is passed from the powder feeder by the powder feeding conduit to the supersonic nozzle portion in which it is accelerated by the air flow at section of the nozzle from the injection point to the nozzle outlet.
The apparatus for gas-dynamic coating of powder materials comprising a source of compressed air connected by a gas conduit to a heating unit, a powder feeder and a supersonic nozzle, said gas heating unit directly connected to the inlet of said supersonic nozzle and said supersonic nozzle being connected through a conduit to the powder feeder outlet, wherein the powder feeder is not hermetically sealed and the cross-section of the supersonic nozzle at the juncture of the nozzle and the powder feeder conduit is made according to the following requirements:
