US. 2004000490 Chang, S. A method to mark an aluminum object includes the steps selective anodizing and coloring the aluminum substrate; providing a mask with a pattern in the same shape as a m a r k to be formed on the aluminum object; irradiating a portion of the anodized surface of the aluminum substrate with an ultraviolet beam through the pattern until the desired mark is formed on the anodized surface. The color of the mark is lighter than the anodized surface of the aluminum object, or gradually changes to the color of the anodized surface of the aluminum object.

US. 2004001964 (Canon KK) Den, T; Iwasaki, T e t al. A method of manufacturing a nanostructure, which enables cylindrical pores arrayed according to any periodic p a t t e r n to be easily made on a substrate over a large area at a low cost in a short period of time. The method of manufacturing a structure having such pores includes the steps of preparing an opt. aluminum substrate having recesses in its surface, providing a film on the surface of the substrata and anodizing the film.
