Profile, the surface corrosion resistance is not strong, to carry out a surface treatment by anodic oxidation in order to increase the aesthetics of the aluminum corrosion resistance, abrasion resistance and appearance. The main process is: (1) Surface Pretreatment: chemical or physical means to profile surface cleaning, clean bare substrate to facilitate a complete artificial oxide film is dense. You can also get a mirror or matte (matt) surface by mechanical means. (2) anodizing: The surface preparation of profiles, under certain conditions, the substrate surface anodic oxidation to produce a dense, AL203 film porous, strong adsorption force.
