The anodic coatings of galvanized steel are of present interest because of their improved corrosion resistance against the atmospheric corrosion. Investigation were carried out to find suitable conditions for producing anodic coatings of controlled quality on the galvanized steel. The present work was able to obtain coatings of six different colours. Anodized zinc performs significantly better corrosion resistance than the bare galvanized steel as evaluated by the salt fog test.
