摘要
FIELD: electrodeposition of coatings. SUBSTANCE: invention relates to electrolytic deposition of protective inorganic coatings on parts of chemical equipment. Method includes preliminarily treating carbon steel parts by way of applying composition containing (in wt %): potassium permanganate, 3-3.5; magnesium oxide, 2-4; silica powder, 3-4; alumina dust, 35-45; phosphoric acid, 10-14; water, the balance. Thereafter electrolytic microarc treatment is conducted in alkali electrolyte with current density 5-25 A/sq. dm. EFFECT: 2-4 times increased thickness of formed coating and increased its chemical stability. 2 tbl
