The invention relates to an anodization on carbon steel surface. The invention used two mass-produced industrial technologies including thermal spray and anodization methods to modify carbon steel surface of anodization. First, use plasma spray method to spray a layer of aluminum film with a thickness of several hundred on the surface of carbon steel, and then use anodization method to produce an anodic film on the surface of aluminum film. The film can effectively improve the properties of the carbon steel surface, for example, hardness resistance to voltages, coloring, and excellent corrosion resistance.
