Plating: An Introduction


Electrochemistry is used in anodizing to form a layer of Al2O3 (aluminum oxide) on the surface of aluminum and aluminum alloys. Anodic oxidation can enhance corrosion resistance, wear resistance, hardness, and protect the metal surface by changing the surface state and performance of the material.

It is widely used in mechanical parts, aircraft and automobile parts, precision instruments and radio equipment, daily necessities, and architectural decoration for non-ferrous metals such as aluminum, magnesium, and their alloys.
