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.
