Abstract
A housing includes a substrate; an aluminum layer deposited on the substrate; and an oxygen ion implantation layer deposited on the aluminum layer. The oxygen ion implantation layer comprising saturated aluminum oxide. The saturated Al2O3 can improve the compactness of the oxygen ion implantation layer. Thus, the corrosion resistance of the housing can be improved.
Claims13
A housing, comprising:
- a substrate;
