A device housing having 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 is provided. The corrosion resistant layer is an Al&#x2014;C&#x2014;N gradient layer implanted with iridium ions by ion implantation process. The atomic percentages of N and C in the Al&#x2014;C&#x2014;N gradient layer both gradually increase from the area near the aluminum layer to the area away from aluminum or aluminum alloy substrate. Therefore the device housing has a high corrosion resistance. A method for making the device housing is also provided.

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&#x2014;O layer. Then, Gd ions are implanted in the Al&#x2014;O layer by ion implantation process. The atomic percentages of O in the Al&#x2014;O gradient layer gradually increase from the side of Al&#x2014;O gradient layer near the aluminum or aluminum alloy substrate to the other side of Al&#x2014;O gradient layer, away from aluminum or aluminum alloy substrate. Therefore the housing has a high corrosion resistance. A method for making the housing is also provided.
