Title: Housing and method for making the same

Abstract: A housing is provided which includes an aluminum or aluminum alloy substrate, an aluminum layer and a corrosion resistant layer formed on the aluminum or aluminum alloy substrate in that order. The corrosion resistant layer is an Al--O--N layer. Then, Nd ions is implanted in the Al--O--N layer by ion implantation process. The atomic percentages of N and O in the Al--O--N gradient layer gradually increase from nearing the aluminum or aluminum alloy substrate to far away from it. The housing has a higher corrosion resistant. A method for making the housing is also provided.
