The difference between anodizing and plating.

Please consult us when you have trouble with surface treatment.

The essential difference between anodizing and plating is how the coating is formed! Anodizing involves "anodic oxidation treatment," which chemically alters the oxide film through electrochemical participation. The coating consists of a "part that grows inward toward the material" and a "part that grows outward," and it is integrated with the material. It is mainly used for aluminum products to enhance corrosion resistance and appearance. Plating involves electrochemical processing with the metal as the cathode to generate a metallic coating. It is an image of a new metal layer being built up on top of the base material. It is used for decorative purposes and to enhance corrosion resistance.
