Due to the use of modern technology processes, the lightweight aluminum alloys parts are frequently utilized because of their good strength-to-weight ratio and corrosion resistance. In order to improve their appearance and make them more durable, surface finishing processes like anodizing and coating are applied. 

Aluminium Surface Treatment by anodic oxidation is one of the most universally employed methods for treating aluminum alloys. This process consists in the electrochemical oxidation of aluminum alloys in a liquid medium, which forms a coating that is both corrosion resistant and non-oxidizing. The anodic oxide layer is rigid, high wear-resistance, inhibited rusting, and low friction. Moreover, custom anodizing provides the ability to create certain textures and colors to the surface of aluminum. This makes it ideal for the use in military vehicles, aircraft, buildings, and other industries where functional and aesthetic elements are equally important.

Spray coating is yet another sophisticated coating technology involving the application of a protective or decorative coating onto the surface of aluminum using a spray gun. With this approach, the finish can be altered such that it can either be matte or glossy, and it can also improve the UV, chemical, and weathering resistance of the component. Electrostatic Powder Coating, a subtype of spray coating, applies negative charge to aluminum, resulting in attachment of the dry powder paint due to electrostatic attraction. The coated aluminum is subsequently heated to achieve durable coating.

To sum up, anodizing and coating have proven to be advanced treatment processes that greatly improve the corrosion protection and beauty of aluminum alloy components. These advanced technologies not only increase the life cycle of the components, but also meet the ever demanding marketing aesthetics. With modernization of manufacturing technologies, it is expected that the incorporation of advanced surface treatments for aluminum alloy components will be even more effective for design and more frequent than it is now.
