Abstract

Anodic treatment of Al (alloy) is carried out in an electrolyte comprising (g/l) 3-100 sulphosalycilic acid, 20-80 maleic acid and 2-20 boric acid at 30-70 V and 0.5-5 A/dm2 current. The reducing agent is 5-50 g/l ascorbic acid and 0.5-2 g/l sulphuric acid. The produced oxide powder layer is treated by usual method
