Some common surface finishes for aluminum coils in the aerospace industry include anodizing, chromate conversion coating, and primer coating. Anodizing is a process that creates a protective oxide layer on the surface of the aluminum, providing enhanced corrosion resistance and durability. Chromate conversion coating, also known as chemical film coating, forms a thin layer on the aluminum surface that provides corrosion resistance and improves adhesion for subsequent coatings. Primer coating is typically applied on top of anodizing or chromate conversion coating to provide additional protection and enhance the adhesion of subsequent paint layers. These surface finishes are important in the aerospace industry as they help to protect the aluminum coils from corrosion and ensure their longevity in harsh environments.
