anodizing, method of plating metal for such purposes as corrosion resistance, electrical insulation, thermal control, abrasion resistance, sealing, improving paint adhesion, and decorative finishing. Anodizing consists of electrically depositing an oxide film from aqueous solution onto the surface of a metal, often aluminum, which serves as the anode in an electrolytic cell. Plate properties such as porousness, abrasion resistance, colour, and flexibility depend on the type, concentration, and temperature of the electrolyte, the strength of the electrical current and the processing time, and the type of metal being plated. In the most common type of anodizing, which uses a 15 percent sulfuric acid bath, dyes can be introduced into the oxidation process in order to achieve a coloured surface. Aluminum that has been anodized and coloured in this way is used widely in giftware, home appliances, and architectural decoration.
