Anodizing is an electrochemical process that enhances the natural oxide layer on the surface of metals, primarily aluminum. This process increases corrosion resistance, improves durability, and allows for better adhesion of paints and dyes. Anodized surfaces are often more resistant to wear and can be colored for aesthetic purposes. During anodizing, the metal is submerged in an acid electrolyte bath and an electric current is applied. This causes oxygen to react with the metal, forming a thicker oxide layer. The result is a protective coating that is both functional and visually appealing, making anodized products popular in various industries, including aerospace and automotive.
