FIELD: technological processes.
SUBSTANCE: invention relates to application of coating by spraying plasma in dynamic vacuum and may be employed in plasma metallurgy, aircraft and space vehicle industry. Plasma flow is directed with applied powder to surface of any rotating part, located in low pressure area. Permeating gas is pumped out in order to maintain dynamic vacuum. Rotating part is blown with cooling gas from side opposed to plasma flow supply. Blowing of cooling gas is performed without mixing flows of cooling gas and plasma. Blowing is performed at distance less than half diameter of rotating part, and total pressure of cooling gas is provided less or equal to full pressure of plasma.
EFFECT: production of spray coating in amorphous state, which in turn enables application coatings of larger thickness upon parts.
