Abstract
The process of covering AMg6 aluminum alloy by zirconium-containing coatings, which are comparable with chromate coatings due to their corrosion stability and protective capacity and can be used as alternative, is developed. Non-toxic immunizing TS-1 sealer is developed. Protective capacity of zirconium-containing coatings sealed for 60-120 s. in aqueous liquid containing 6-7.5 g/l TS-1 is proved to reach 120 s.
