摘要
A solid carbide milling cutter has a substrate of hard metal and a multi-layer coating deposited at least to surface regions that contact a workpiece during a milling operation. The multi-layer coating includes a single-layer or a multi-layer functional layer deposited directly on the substrate surface and a single-layer or a multi-layer covering layer deposited on the functional layer. The functional layer has one or more layers of TixAl1-xN with 0.3≦x≦0.55. The covering layer has one or more layers of ZrN. The functional layer and the covering layer are deposited by HIPIMS, wherein during the deposition of the functional layer power pulses are applied to each sputtering target consisting of material to be deposited, which power pulses transfer an amount of energy to each sputtering target that exceeds a maximum power density in the pulse of ≧500 W/cm2.
