FIELD: application of reinforcing, protective and decorative coats on articles in vacuum.
SUBSTANCE: proposed method includes electric arc spraying of cathode target and treatment of metal plasma flow in crossing electric and magnetic fields in cavity of additional anode of electric arc device. Dependent discharge of reaction and/or inert gas is ignited inside cavity of this additional anode. Metal plasma flow is additionally treated while passing through this discharge. Flow containing ions of gas and ions of material of cathode target settles on surface to be coated; potential of article is below potential of additional anode by 2000 V.
EFFECT: enhanced adhesion strength; high rise of coats at stoichiometric connections.
