FIELD: mechanical engineering, in particular, processing of article surfaces.
SUBSTANCE: method involves providing microarc oxidation of articles from aluminum, titanium, zirconium and alloys thereof in alternate current mode in combined electrolyte based on sodium silicate 80-120 g/l, sodium phosphate 5-10 g/l and sodium hydroxide 5-15 g/l for 5-80 min at current density of 5-30 A/dm2 and voltage of 120-220 V.
EFFECT: increased oxide layer growth rate, reduced porosity, increased surface microhardness and wider range of application of materials used.
