Application of electric arc spraying technique to enhance corrosion resistance of steel structures on ships

Abstract

Steel structures on ships operate in hostile environments and can be subject to severe corrosion. Composite coatings consisting of aluminium arc sprayed nd organic layers can effectively increase the corrosion lifetime of such structures. The composite layer developed consists of an electric arc sprayed aluminium layer followed by a layer of organic paint to seal the aluminium coating, followed by a layer of a conventional ship’s paint.
