FIELD: electrical engineering.
SUBSTANCE: according to the method, one introduces into the electrolyte nano-dispersed chrome diboride powder with particle size 40-70 nm and oxidation no more than 12·10-7 kg of oxygen /m2 of the surface in an amount of 6-10 kg/m3 and in the form of an electrolyte-and-powder paste with chrome diboride content no more than 65 wt %, such paste having undergone ultrasonic treatment at s frequency no less than 20 kHz; then the coating is sedimented at a temperature of 323-333 K and cathode current density equal to 0.9-1.0 kA/m2 and annealed in vacuum at a temperature of 873-1073 K during 50-75 min.
EFFECT: improved microhardness, wear resistance, corrosion resistance of the coating combined with reduction of its production costs.
