Abstract
A cutting tool insert includes a body of cemented carbide, cermet, ceramics, high speed steel (HSS), polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN), a hard and wear resistant coating is applied, grown by physical vapour deposition (PVD) such as cathodic are evaporation or magnetron sputtering. The coating includes at least one layer of (ZrAl)N with 0.05<x<0.30 with a thickness between 0.5 and 10 μm. The layer has a nanocrystalline columnar microstructure consisting of a single cubic phase or a mixture of hexagonal and cubic phases. The insert is particularly useful in metal cutting applications generating high temperatures with improved edge integrity.
