HOUSING AND METHOD FOR MAKING THE SAME

摘要

A housing, comprising: a substrate; a micro-arc oxide film formed on the substrate; and a plurality of grooves formed on the oxide film; wherein all or part of the oxide film is polished to present a glossy appearance, the grooves are formed on the polished region of the oxide film. A method for making housing, comprising: providing a substrate; micro-arc oxidizing the substrate to form a micro-arc oxide film on the substrate; polishing at least part of the micro-arc oxide film; and etching the polished surface of the micro-arc oxide film to form grooves in the polished surface.
