FIELD: technological processes.
SUBSTANCE: invention is related to technology for application of strengthening, protective and decorative coats in vacuum onto products for giving them different functional properties and colour shades. Method substance consists in the fact that prior to connection of electric arc generator, protective screen is installed into vacuum chamber, which prevents plasma flux getting onto products into vacuum chamber. Plasma flux that occurs in initial period of time after connection of electric arc generator, gets on screen, and after this period of time elapses, screen is removed.
EFFECT: improved adhesion strength of coat, lower dispersion of adhesion strength and improved quality of coats.
