The Anodizing method is used to form an oxide layer on the surface of the metal parts, which is one of the mainstream surface treatment methods in the rapid manufacturing industry. The oxide layer can play a protective role, and according to the demand, it can also give the workpiece a variety of dazzling metal colors.
Anodizing aluminum is an electrolytic oxidation process in which the surface of aluminum is usually converted into an oxide film that has protective, decorative, and other functional properties.
The anodizing coating obtained by the sulfuric anodizing process has a colorless and transparent appearance with a thickness of 5-20um. It has high hardness, many pores, and strong absorbability, which is conducive to dyeing. After closed treatment, it has high corrosion ability and is mainly used for protection and decoration purposes.
The process of anodizing coating formation is actually a hydrolysis process:
