FIELD: method of coating application by plasma spraying on pieces, that have figure of rotation shape. SUBSTANCE: method provides for gas pumping out in direction coaxial with plasma spray, coating material spraying. In the case opposite side of piece before spraying and in process of its realization is blasted with argon heated up to temperature of 60 -100 C with gas usage of 0.5 - 1.2 cubic meter per hour and with cooling during piece rotation. EFFECT: improved process. 5 dwg
