Anodizing is an electrochemical process that enhances the natural oxide layer on the surface of metals, primarily aluminum. This process not only increases corrosion resistance but also improves wear resistance and allows for better adhesion of paints and dyes. Anodized surfaces can be colored, making them visually appealing for various applications, from aerospace components to everyday items like cookware. During anodizing, the metal is submerged in an acid electrolyte bath and an electric current is passed through it. This causes oxygen to react with the metal, forming a thicker oxide layer. The result is a durable, protective finish that can withstand harsh environments, making anodizing a popular choice in industries such as automotive and construction.
