Abstract:
A process for surface treating aluminum or aluminum alloy comprises the following steps. Providing a substrate made of aluminum or aluminum alloy. The substrate is treated with a chemical conversion treatment solution containing molybdate as the main film forming agent, to form a molybdate conversion film on the substrate. Then, a ceramic coating comprising refractory compound is formed on the molybdate conversion film by physical vapor deposition.
