| 摘要 |
<p>The present invention relates to a coated cutting tool and a hard and wear resistant coating for a body (1) comprising at least one metal based nitride layer (3) with improved high temperature performance where said layer is (ZrxCr1-x-y-zAlyMez)Na with 0.55 < x < 0.85, 0.05 < y < 0.45, 0≤z< 0.20, 0.95 < a < 1.10, and Me is one or more of the elements: Y, Ti, V, Nb, Ta, Mo, W, Mn or Si, comprising of a single cubic phase or a single hexagonal phase or a mixture thereof, preferably with a cubic phase of a sodium chloride structure, with a thickness between 0.5 µm and 15 µm. The layer is deposited using cathodic arc evaporation and useful for metal cutting applications generating high temperatures.</p> |
