As an electrochemical process, anodizing changes the surface of metals to make them more durable to wear, corrosion-resistance, and to give them an attractive finish. The process increases the natural oxide layer that coats metal parts, though it is most commonly used with aluminum and its alloys. This aluminum oxide results in a thin protective layer that protects and covers the top metal layer. Though anodization processes exist for other nonferrous metals – such as zinc, magnesium and titanium – and there are processes that use aluminum plate to anodize color into other metals, what follows mainly addresses the color anodization process used for aluminum, with a more in-depth focus upon hard coat anodized color dyeing.
