FIELD: electricity.
SUBSTANCE: considered by the invention, plasma jet consists of a housing, tungsten cathode and nozzle-type anode linked with the housing and provided with an output channel. The output channel of nozzle-type anode is made cone-shaped and enlarged to its end. The angle of cone generatrix to the longitudinal axis of the nozzle-type anode is within 8°-11°. Besides, the nozzle-type anode is bimetal in the area of output channel and represented with interconnected copper wall and molybdenum shield. The thickness of molybdenum shield is 0.25÷0.4 from the copper wall thickness in the cross section.
EFFECT: stable burning of electrical arch in case copper penetration into sprayed metal, powder is avoided when powder is produced from nickel alloys granules from nozzle-type anode surface.
