Prodn. of surface structure on anodised oxide coating of an iron

Surface structure, partic. lettering, is applied to the sole or shoe of an iron which has an anodised layer (312) of anodised Al or Al alloy. A laser is used to form at least one line (313) by removal of the anodised layer almost completely. In the remaining anodised layer, a conversion layer is for...

Beschreibung
Zusammenfassung:	Surface structure, partic. lettering, is applied to the sole or shoe of an iron which has an anodised layer (312) of anodised Al or Al alloy. A laser is used to form at least one line (313) by removal of the anodised layer almost completely. In the remaining anodised layer, a conversion layer is formed at least of Al oxide, Al or Al alloy and incorporated N, producing a corrosion layer with a thickness of 20 nm to 400 nm. The laser is pref. a Nd-YAG laser and is focused to produce a focal spot of 40-500 mu for removal of anodic layer.
