Marking of an anodized layer of an aluminum object |
摘要 |
A marking (3 to 5) is provided in a surface (8) of an element (1) which comprises a substrate (6) of aluminum or an alloy thereof and an anodized outer layer (7) in that a region (10) of the surface (8) is irradiated with a laser beam such that at least one visual property of the surface (8) in said region (10) is changed and a visual marking (3 to 5) is obtained which is observable to the human eye. The laser beam penetrates the anodized outer layer (7) at least to a major degree and induces the change in the at least one visual property substantially locally only in a zone (9) where the anodized outer layer (7) adjoins the substrate (6).
