COATING STRUCTURE HAVING CORROSION RESISTANCE |
摘要 |
The coating structure having a corrosion resistance of the invention contains a formation film formed on the surface of an aluminum alloy material. The formation film is subjected to a zirconium phosphate treatment. Because the zirconium phosphate reacts with an oxide film on the surface of the aluminum alloy to form a zirconium boehmite layer and to increase the adhesion of the coating material, a corrosion resisting structure is obtained without need of a sealing treatment while restraining the increase of the product cost. Also, a primer layer is formed on the outer surface of the formation film and the primer layer is composed of phosphomolybdic acid.
