Abstract
Tool with optional wear-protection coating has, as an outer layer arranged on top of the substrate body or wear-protection coating, a single-layer wear-recognition layer (A) or a multilayer wear-recognition layer (B) comprising at least 4 individual layers arranged one above another, said layer or layers being produced by depositing elemental metals, metal alloys or electrically conductive metal compounds with a PVD process. Individual layer of (A) or at least one individual layer of (B) contain at least two different metals, the wear-recognition layer comprises a region produced by anodic oxidation from the upper surface down to a penetration depth that does not extend over the entire thickness of the wear-recognition layer, and the individual layer of (A) or the at least one individual layer of (B) has at least two different phases before the anodic oxidation and in the regions of the wear recognition layer that are not anodically oxidized.
