Which method is commonly used for corrosion protection of aluminum structures?

Anodizing the surface is a highly effective method for corrosion protection of aluminum structures. This electrochemical process enhances the natural oxide layer on aluminum, making it thicker and more robust against environmental factors that lead to corrosion. The anodized layer not only provides excellent corrosion resistance but also increases the wear resistance of aluminum, enhancing its durability for use in aviation and other applications where lightweight and strength are critical.

In addition to corrosion protection, anodizing can also be done in various colors for aesthetic purposes, and it allows for better adhesion of paints and adhesives, contributing to the overall longevity and performance of aluminum structures. By creating a more durable barrier against oxidation, anodizing significantly prolongs the service life of aluminum components used in aircraft and other demanding environments.
