Abstract
An anti-abrasive layer which is useful for tools contains nitrides of the metal elements Cr, Ti and Al; and at least one element (κ); wherein a proportion of Cr in said anti-abrasive layer is more than 65 at %; a proportion of Al is 10 to 25 at %; and a proportion of Ti is 10 to 25 at %, based on a total amount of metal atoms in said anti-abrasive layer.

1 more element
An anti-abrasive layer, comprising:
- nitrides of the metal elements Cr, Ti and Al;
- and
- a two strata layer structure;
- wherein a bottom stratum comprises a base layer selected from the group consisting of a (TiAlCr)N layer, a (TiAlCrκ)N layer and combinations thereof,
- wherein said bottom stratum is covered by a CrN top layer as upper stratum;
- wherein the base layer comprises
- more than 30 at % of Cr;
- 15 to 35 at % of Al;
- and
- 16 to 40 at % of Ti,
