ABSTRACT:
Plated high strength steel articles having a metallic plated coating exhibit high corrosion resistance and low hydrogen reembrittlement characteristics when an acrylic polymeric coating, such as a methyl methacrylate polymer is applied to the aritcle. A corrosion inhibitor and adhesion promoter such as benzotriazole and a leveling agent such as an alkyd polymer can be incorporated with the acrylic polymer in minor proportions to further enhance the corrosion resistance characteristics of the coating. A benzotriazole-containing acrylic polymer formulation also enhances the corrosion resistance characteristics of an unplated metal substrate.
