Corrosion behaviour of aluminium sprayed mild steel and aluminised steel

Abstract

Use of aluminium is coming into vogue in the canning industry. However, the very much higher cost of aluminium than tin plate inhibits the scope for substitution of tin plate by aluminium. It is therefore of interest to examine whether steel coated with aluminium by any of the known methods is suitable for manufacture of containers for canned products. Aluminium‐coated steel can be considered only if the coating has a more negative potential than the base metal. In a study of the behaviour of sprayed aluminium coatings on mild steel in sodium chloride solutions at different pHs, Ross has pointed out that sprayed aluminium (99.5%) is more negative than steel in neutral and alkaline solutions. In this paper, the potential relationships between steel, steel sprayed with aluminium, and aluminised steel in some organic acids commonly present in food stuffs are discussed.
