A coated article includes a substrate, an anti-corrosion layer formed on the substrate, a decorative layer formed on the anti-corrosion layer. The substrate is made of aluminum or aluminum alloy. The anti-corrosion layer is a silicon layer. The coated article has improved corrosion resistance.
摘要:
A process for treating the surface of aluminum or aluminum alloy comprises providing a substrate made of aluminum or aluminum alloy. Then a silane-based hybrid film doped with cerous salt is formed on the substrate by sol-gel process, and a ceramic coating comprising refractory compound is formed on the silane-based hybrid film by physical vapor deposition.
