Anodizing


Anodizing is an electrochemical process that converts the surface of a metal into a durable, corrosion-resistant oxide layer. In the context of space and astronautical engineering, anodizing is commonly used to protect aluminum components from the harsh environment of space. The anodized layer provides a barrier against corrosion, wear, and abrasion, and can also be used as a base for paint or other coatings. Anodizing can be performed using a variety of methods, including sulfuric acid anodizing, chromic acid anodizing, and hard anodizing. The choice of method depends on the specific application and the desired properties of the anodized layer.
