FIELD: electrochemical deposition of oxide wear-resistant coatings on aluminum and its alloys with improved antifriction and antiscuff properties by microarc anodizing. SUBSTANCE: method includes deposition of coating by microarc anodizing with the help of introduction into its porous structure from electrolyte composition of inorganic layer solid lubricating material with dispersity of 5-50 mcm ensuring rotaprint lubrication of friction surfaces. Electrolyte contains, g/l: potassium hydroxide, 2-3; sodium water glass, 8-10; hydrogen peroxide, 2.5-10; molybdenum disulfide, 15-25; water, the balance. The method makes it possible to improve antifriction and wear-resistant properties in three times. EFFECT: increased service life of friction units. 3 cl, 2 tbl
