METHOD OF ECONOMY PLASMATIC ULTRASONIC SPATTER OF HIGH-DENSITY POWDER COATINGS AND PLASMATRON FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2009 - IPC C23C4/12 H05H1/00 

FIELD: metallurgy.

SUBSTANCE: plasmatron for economical plasma spraying is outfitted by attachment or elongated anodic nozzle. Cooling of attachment or elongated anodic nozzle can be as separately as collateral. According to declared method powder is fed into anodic nozzle, is accelerated and heated in attachment channel or in elongated anodic nozzle. Adhering is removed by means of selection of process-dependent parametres, herewith length of attachment channel or elongated anodic nozzle must be not more than 15 diametres, channel diametre can be changed in the same direction as powder flow not more than 1.1÷1.2 times.

EFFECT: decreasing of required arc power, increasing of material utilisation.
