Abstract
An aluminum or aluminum alloy article is described. The aluminum or aluminum alloy article includes an aluminum or aluminum alloy substrate, a barrier layer formed on the substrate, a color layer formed on the barrier layer, and an insulation layer formed on the color layer. The barrier layer and the color layer are formed by vacuum sputtering. The barrier layer is a layer of silver-aluminum-oxygen-nitrogen. The insulation layer is an external layer of the aluminum or aluminum alloy article.
