Layer system for the formation of a surface layer on a surface of a substrate and coating method for the manufacture of a layer system

Abstract

The invention thus relates to a layer system () for the formation of a surface layer on a surface of a substrate, in particular on the surface of a tool, in particular on the surface of a shaping tool, wherein the layer system includes at least a first surface layer of the composition (VMeMX)(NCO), where (a+b+c+d)=α, α=100%, with respect to the atoms V,Me,M,Xpresent in the layer, (u+v+w)=β. β=100 with respect to the atoms N, C, O present in the layer, with the sum of all the atoms in the layer (α+β)=100 at %, where 40≦α≦80 at % applies, and where Meis at least one element from the group of chemical elements including Zr, Hf, Nb, Ta, Mo, W, Ni, Cu, Sc, Y, La, Ce, Pr, Nd, Pm, Sm of the periodic system of chemical elements and Mis at least one element of the group of chemical elements including Ti, Cr, and Xis at least one element from the group of chemical elements including S, Se, Si, B of the periodic system of elements, where 0≦u≦100, 0≦v≦100 and 0≦w≦80. In accordance with the invention 50≦a≦99, 1≦b≦50, 0≦c≦50 and 0≦d≦20.
