How does the anodizing process work ？

1. Preparation and cleaning: A uniform and smooth surface is essential for the application of the anodized layer. You can achieve this through mechanical treatment and chemical cleaning. Mechanical surface treatment such as grinding and polishing that remove surface irregularities and defects. While alkaline or acid cleaning removes grease, oil, dirt and any other contaminants, followed by rinsing with deionized water to remove residual cleaning agents. Therefore, etching can be further cleaned to peel off the thin surface layer and create a uniform matte effect.

2. Electrochemical process: The part to be anodized next becomes the anode, and the other highly conductive metal becomes the cathode, and both are immersed in the electrolytic cell. When current flows through this electrolytic device, the anode oxidizes and loses electrons. During the electrolysis process, the metal surface is oxidized to form a dense oxide film. This oxide film is very hard and can protect the metal from further corrosion.

3. Coloring (optional): After the oxide film is formed, it can be dyed to give the metal surface a different color.

4. Sealing: The corrosion resistance and wear resistance of the oxide film can be further enhanced by sealing.
