Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of treating a metal surface comprising: forming a uniformly flat metal surface by polishing the metal surface until the metal surface has a surface roughness of about 0.1 micrometers or less; forming a textured metal surface by texturing and then polishing the uniformly flat metal surface such that the textured metal surface has a plurality of substantially isolated and rounded peaks separated by a plurality of valleys, wherein the texturing and p…
