FIELD: technological processes; glass industry.

SUBSTANCE: invention relates to the field of decorating glass and articles, namely to a method of applying aluminum on glass articles made therefrom, and can be used in the glass industry at the technological stage of applying decorative coatings on glass household goods. Air is evacuated from the sputtering chamber to vacuum of 0.007 Pa and the basket with glass articles is rotated at a rotation speed of basket of 2 rpm. Then, argon gas is fed at pressure of 0.06 Pa and a source of ion cleaning of the surface of glass articles is switched on at the following parameters: anode voltage of 3 kV, anode current of 200 mA, and cleaning time of 20 minutes. Surface layer of glass articles is cleaned by bombardment in high vacuum with argon ions with energy of 100–100,000 eV, which spray the surface layer with removal of adsorbed atoms and oxides. Then, magnetron sputtering sources with installed aluminum targets are switched on. Then, at argon gas pressure of 0.05 Pa, a layer of aluminum is applied for 30 minutes at the following parameters: current of sources is 10 A, voltage is 380–420 V. Then, a layer of preserved epoxy lacquer is applied on the aluminum layer. Thereafter, the glass articles are placed in an annealing muffle furnace and held at temperature of 150 °C for 12 minutes.

EFFECT: high strength of the obtained decorative coating.
