    摘要: A housing includes a substrate made of aluminum or aluminum alloy, an ion implantation layer formed on the substrate, and a vacuum coated layer formed on the ion implantation layer. The ion implantation layer is implanted with one or more ion species selected from the group consisting of nitrogen ion, oxygen ion, and boron ion and is substantially comprised of one or more selected from the group consisting of aluminum nitride, aluminum oxide, and aluminum boride. The implanted ions can improve the compactness of the ion implantation layer. Thus, the corrosion resistance of the housing can be improved.
