The anodizing of aluminum is an electrolytic oxidation process in which the surface of aluminum and its alloys is usually converted into an oxide film, which has protective, decorative and other functional properties. Anodic oxidation of aluminum from this definition includes only the process of forming anodic oxidation film.Generally speaking, the anode is made of aluminum or aluminum alloy as the anode, and the cathode selects the lead plate, and puts the aluminum and lead plate together in an aqueous solution, which contains sulfuric acid, oxalic acid, chromic acid, etc., for electrolysis, so that the surface of aluminum and lead plate forms a kind of oxide film.The metal or alloy parts are used as anodes and their surfaces are formed into oxide films by electrolysis.Metal oxide film changes the surface state and performance, such as surface coloring, improve corrosion resistance, enhance wear resistance and hardness, protect the metal surface, etc.For example, anodization of aluminum is carried out by placing the aluminum and its alloys in the corresponding electrolytes (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode under specific conditions and applied current.
