Abstract

A hard and wear resistant coating for a body includes at least one metal based nitride layer having improved high temperature performance. The layer is (Zr1-x-zSixMez)Ny with 0<x<0.30, 0.90<y<1.20, 0≦z<0.25, and Me is one or more of the elements Y, Ti, Nb, Ta, Cr, Mo, W and Al, comprised of a single cubic phase, a single hexagonal phase or a mixture thereof, with a cubic phase of a sodium chloride structure and a thickness between 0.5 μm and 15 μm. The layer is deposited using cathodic arc evaporation and is useful for metal cutting applications generating high temperatures.
