    摘要： The present invention relates to a coated cutting tool for metal machining with a 2.0-20 µm thick PVD coating, having both the wear resistance of a coating of homogeneous layers and the toughness of a multilayer coating, comprising a first (Me c1 ,Me c2 ) (C,N,O) layer where Me c1 is one or more of the elements in the transition metal group IV-VI, Al and Si and Me c2 is one of the elements in the transition metal group IV-VI, 1.0-4.5 µm thick, a second (Me d1 ,Me d2 ) (C,N) layer where Me d1 is one or more of the elements in the transition metal group IV-VI, and Al and Si and Me d2 is one of the elements in the transition metal group IV-VI, and Y, 0.5-4.5 µm thick, and in between the first and the second layer, an (Me e1 ,Me e2 ) (C,N,O) layer where Me e1 is one or more of the elements in the transition metal group IV-VI, Al and Si and Me e2 is one of the elements in the transition metal group IV-VI and Y, 0.1-1.0 µm thick, where the thickness of the in between layer is less than 0.5 times the thickness of thinnest of the first and the second layer and the in between layer has a composition differing from the first and the second layer, and a method of making thereof.
