METHOD OF APPLYING TITANIUM CARBONITRIDE ON GLASS ARTICLES Russian patent published in 2022 - IPC C23C14/06 C23C14/18 C23C14/24 C23C14/35 

FIELD: glass industry.

SUBSTANCE: invention relates to decoration of glass and articles made from it, and namely to a method of applying titanium carbonitride on glass articles, and can be used in glass industry. Air is evacuated from the sputtering chamber to vacuum of 0.02 Pa and the basket with glass articles is rotated at a speed of rotation 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 the magnetron sputtering source with VT1-0 titanium targets is switched on, and at the argon gas pressure of 0.05 Pa, an opaque reflecting titanium layer is applied for 20–25 minutes at the following parameters: source current 9–10 A and voltage 380–400 V. Then, arc evaporator with VT1-0 titanium target is switched on. Reactive gas is fed into the chamber in form of a ready mixture of nitrogen and acetylene in proportion of 70–30 % with pressure of 0.15 Pa, and at current of inverter sources of 130–150 A, a layer of titanium carbonitride is deposited on glass products for 15 minutes.

EFFECT: higher strength of decorative coating.
