FIELD: powder metallurgy, namely processes for applying coatings of metal powders onto article surfaces.
SUBSTANCE: method comprises steps of applying powder material onto surface of part; heating part till time moment of achieving melting temperature of powder material on butt of part surface with powder material; sintering powder material; after achieving melting temperature of powder material on butt with part surface, realizing isothermal soaking. Sintering is performed after powder material surface achieves sintering temperature that is kept constant during isothermal soaking by positive cooling of free surface of powder material. In variants of invention free surface of powder material is positively cooled by means of shield gas.
EFFECT: enhanced quality of coating, simplified technique for applying it.
