METHOD FOR MAKING HOUSING AND HOUSING THEREOF

摘要

A method for making housing, comprising: providing a substrate; etching the substrate to form a plurality of grooves on a surface of the substrate; micro-arc oxidizing the substrate to form a micro-arc oxide film in the grooves and on the surface of the substrate; and polishing the micro-arc oxide film formed on the surface of the substrate. A housing, comprising: a substrate, the substrate having a plurality of grooves defined therein; and a micro-arc oxide film formed on the surface of the substrate and in the grooves; wherein the oxide film formed on the surface of the substrate is polished to present a glossy appearance.
