Body with a metal based nitride layer and a method for coating the body |
| 摘要 |
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. |

1. A hard and wear resistant coating for a body, the coating comprising:
at least one metal based nitride layer deposited on the body by cathodic arc evaporation, wherein said at least one metal based nitride layer is (Zr1−x−zSixMez)Ny with 0<x<0.15, 0.90<y <1.10, 0≦z<0.25, and Me is one or more of the elements Y, Ti, Nb, Ta, Cr, Mo and W, the at least one metal based nitride layer being selected from the group of a cubic phase of a sodium chloride structure, a single cubic phase, a single hexagonal phase, and a mixture thereof, the at least one metal based nitride layer having a thickness between 0.5 μm and 15 μm, and TC(200)>1.5 and simultaneously TC(111), TC(220) and TC(311) all being <1.5 wherein TC(hkl) is determined from XRD data as follows:TCmeas(hkl)=Imeas(hkl)I0(hkl)[1n∑n=1nImeas(hkl)I0(hkl)]-1wherein
Imeas(hkl) is a measured intensity of the (hkl) reflection and Io(hkl) a standard intensity according to JCPDS card no. 035-0753, and n=4 is the number of (hkl) reflections used in the calculations. |
