Abstract: A 5052 aluminum-magnesium alloy is a non-heat treatable aluminum alloy which has good corrosion resistance in petrochemical and marine environments. This alloy also has high strength and is good weldability, so it is widely used in various application such as ship hull, automobile parts, fuel tank, and oil pipes. Anodization is a basic method for improving corrosion resistance of aluminum alloy in both general atmosphere and severe environment. However, not only corrosion but also biofouling is a concerned problem of marine application. Antifouling behavior of 5052 aluminum alloy in different conditions such as as-received (neither anodized nor painted), anodized, painted, and anodized followed by painted in brackish water were investigated. Anodization did not improve antifouling behavior of aluminum alloy 5052 as algae without colonization of barnacles were found on non-anodized and anodized 5052 surfaces. In contrast, the painted without anodization and the anodized followed by painted conditions revealed colonization of barnacles without algae. Anodization might affect the painted surface since the growth rate of barnacles on anodized followed by painted was lower than the painted sample without anodizing
