Thin films of material bonded to metals in order to add specific surface properties, such as corrosion or oxidation resistance, color, attractive appearance, wear resistance, optical properties, electrical resistance, or thermal protection. In all cases proper surface preparation is essential to effective bonding between coating and basis metal, so that coated metals can function as duplex materials. This article discusses various methods of applying either metallic coatings (see table) or nonmetallic coatings, such as vitreous enamel and ceramics, and the conversion of surfaces to suitable reaction-product coatings. For other methods for the protection of metal surfaces See also: Cladding; Electroless plating; Electroplating of metals; Lacquer; Paint and coatings
