FIELD: application of coatings. SUBSTANCE: method involves applying protective-ornamental coating, preferably coating based on oxides of titanium, chromium, tungsten, zirconium, hafnium or vanadium, as well as implantation phases selected in the group of carbides, nitrides and carbon nitrides of above mentioned metals, by applying coating to metal or nonmetallic surface through coat-spraying of targets from active metals, their alloys or composite materials by ionic bombardment in glow discharge; providing deposition of sprayed particles onto surface of article to be coated. Spraying is effectuated in the mixture of inert and reactive gases, which are supplied separately into reaction volume, with reaction volume being preliminarily filled with inert gas to pressure value of (3.0-3.5)·10-3 mm. of mercury column. Water vapors, carbon dioxide, air or oxygen-containing gas mixture used as reactive gas is supplied to zone adjacent to surface of article heated to 300-350 C till pressure in reaction volume reaches (6.0-10)·10-3 mm. of mercury column. Spraying time is controlled within the range necessary for obtaining ornamental effect of predetermined intensity and required range of color tints. EFFECT: increased efficiency of method by increased speed of obtaining ornamental coatings, improved safety of process by reduced fire and explosion protection in case oxygen-containing compositions and water vapors and not pure oxygen are used as reactive gas.
