Abstract
A monolayer or multilayer nitridic or carbonitridic hard material coating contains Al and Ti and at least one of the layers comprises the composition (AlTiRuMe) (NC), 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 is 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.
