nodizing is a conventional surface treatment technology is the use of electrochemical methods, in the corresponding electrolyte and specific process conditions, using metal or metal alloy as anode, stainless steel, iron or nickel as the cathode, through the external current, metal or metal alloy surface layer of stable oxide film process. Generated oxide film can improve the substrate surface corrosion resistance, wear resistance and hardness. Before anodizing, the use of mechanical or compound solution on the surface of the metal and alloy oil and rust removed. According to the different anodizing electrolyte can be divided into different categories, mainly sulfuric acid anodic oxidation, anodic oxidation of oxalic acid, chromic acid anodizing and hard anodizing law, under different acidic conditions can be anodized with different performance membrane. Using natural hair color, electrolysis color coloring or dye impregnation method for coloring anodic oxide film. After coloring the micro pores of the oxide film to be closed, after the closure of the treated surface becomes uniform without holes, the formation of dense oxide film.
