摘要：
The invention relates to a mono- or multilayer nitride or cabonitride hard material coating that contains Al and Ti, at least one of the layers comprising the composition (AlxTiyRuzMev)(NaC1-a), with 0.45 ≤ x ≤ 0.75, 0.20 ≤ y ≤ 0.55, 0.001 ≤ z ≤ 0.10. 0 ≤ v ≤ 0.20, 0.8 ≤ a ≤ 1.1, Me being selected from the group of elements including Si, B, W, Mo, Cr, Ta, Nb, V, Hf, Zr. The Ru-containing hard material coating has a decreasing hardness shifted towards the higher temperature range and therefore an improved wear resistance.
