FIELD: mechanical engineering and other branches of industry, in particular, processing of article surfaces.
SUBSTANCE: method involves providing microarc oxidation of articles from aluminum, titanium, zirconium and alloys thereof in direct current mode in combined electrolyte based on liquid glass 80-120 g/l, sodium chromate 2-10 g/l and sodium hydroxide 2-10 g/l for 10-90 min at current density of 5-25 A/dm2 and voltage of 120-500 V.
EFFECT: increased oxide layer growth rate, reduced porosity, increased surface microhardness and corrosion resistance, and wider range of application of materials used.
