FIELD: metallurgy.
SUBSTANCE: method of forming the microrelief on the surface of metal articles includes treatment of article surface in vacuum with concentrated flow of energy, localised in cathode spots of cathode spots of vacuum-arc discharge moving along the article surface, burning between the article being the cathode and anode, in this case surface treatment of the article is carried out in vacuum pressure range from 10 Pa to 200 Pa.
EFFECT: simplification of microrelief formation on the surface of metal articles, elimination of decarburization and oxidation of the treated surface, possibility to process surfaces of complex geometric shape with increase of process efficiency due to high movement rate of cathode spots.
