Beschreibung
Zusammenfassung:	FIELD: spraying apparatus for applying coatings. ^ SUBSTANCE: device comprises power source, housing with the cathode and anode having through opening, system for supplying plasma-generating gas made of openings arranged around the cathode in the cathode holder, washer made of a fire-resistant material, and system for supplying the powder material to be sprayed. The system for supplying the material to be sprayed is made of openings. The cathode and anode are connected with the power source, and the opening in the anode is positioned symmetrically with respect to the axis of the housing. The device for plasma spraying is also provided with the nozzle mounted in series with the anode and washer to define a cylindrical passage for transporting plasma to the system for supplying the powder material set in the nozzle wall. ^ EFFECT: enhanced quality of coating and reduced powder material loss. ^ 2 dwg
