For surface treatment of oxide film on aluminum and its alloys have adornment effect, protection performance and special function, can improve the aluminum and its alloy conductive, thermal conductivity, wear resistance, corrosion resistance, and optical properties, etc. Therefore, the researchers at home and abroad used various methods to treat the surface to improve its comprehensive performance and made great progress. At present, aluminum and its alloy materials have been widely used in buildings, aviation and military fields.

Anodic oxidation

Aluminum anodic oxidation method is the aluminum as anode, placed in the sulfuric acid electrolyte, such as electrolysis anode voltage applied, on the surface of aluminum form a dense layer of Al2O3 film, the film is composed of dense block and columnar structure of the porous layer consisting of double layer structure. During anodizing, the forming process of the oxide film includes the electrochemical generation of the membrane and the chemical dissolution of the membrane. The membrane is formed and grown when the membrane velocity is greater than the dissolution velocity. By reducing the dissolution rate of the film, the density of the film can be improved. The performance of the oxide film is determined by the density of the membrane.
