Abstract
A method to mark an aluminum object (1) includes the steps of: providing an aluminum substrate (10); anodizing and coloring the aluminum substrate; providing a mask (2) with a pattern (25) in the same shape as a mark (15) to be formed on the aluminum object; irradiating a portion of the anodized surface (12) 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.

A method for marking an aluminum object comprising the steps of:
- providing an aluminum substrate;
- anodizing and coloring said aluminum substrate;
- providing a mask with a pattern in the same shape as a mark to be formed on the aluminum object;
- irradiating a portion of the anodized surface of said aluminum substrate with an ultraviolet beam through said pattern until the desired mark is formed on the anodized surface.
A method for marking an aluminum object comprising the steps of:
- providing an aluminum substrate;
- anodizing and coloring said aluminum substrate;
- providing a mask with a pattern, the mask being covered with a coating comprising an ultraviolet absorbing compound for inhibiting ultraviolet light from being transmitted therethrough on all areas except for the area defining the pattern;
- irradiating a portion of the anodized surface of said aluminum substrate with an ultraviolet beam through said pattern until the desired mark is formed on the anodized surface.
A method of marking an aluminum object comprising steps of:
- providing an aluminum substrate;
- anodizing and coloring said aluminum substrate to have color absorbed in a final formed anodized layer;
- and
- decolorizing said anodized layer in a pattern while without jeopardizing/thinning said anodized layer.
