Abstract
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—C—N gradient layer implanted with iridium ions by ion implantation process. The atomic percentages of N and C in the Al—C—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.
