PROCESS FOR SURFACE TREATING ALUMINUM AND ALUMINUM ALLOY ARTICLES |
摘要 |
A process for surface treating aluminum and aluminum alloy articles is provided. The method includes the steps of providing a substrate of aluminum or aluminum alloy material, the substrate having an internal surface and an external surface; machining the external surface of substrate, thereby forming a first surface appearance on the external surface; forming a first oxide coating with a first color on the substrate surface by a first anodizing process; removing at least a portion of the first oxide coating on the internal surface of the substrate to make the substrate electricity conductive; machining the external surface of the substrate, thereby removing at least a portion of the first oxide coating on the external surface and forming a second surface appearance thereon; forming a second oxide coating with a second color on the area of the external surface excluding the first oxide coating by a second anodizing process.
