Abstract

A metal surface treated to have a distinct cosmetic appearance such as an integral layer that is glossy may be used in electronic devices. The surface treatment may include polishing a metal surface, texturing the polished metal surface, polishing the textured surface, followed by anodizing the surface, and then polishing the anodized surface. The metal surface may also be dyed to impart a rich color to the surface.
