权利要求: Claims1. A multilayer coating with layers A and layers B deposited forming a sequence of the type ...A/B/A/B/A... , the layers A being CrN-based layers or CrN layers and the layers B being CrON-based layers or CrON layers, characterized in that the multilayer coating exhibits a modulated ratio of the thicknesses of the A layers and B layers, in a manner that the multilayer coating comprises at least two different coating portions along the whole multilayer coating thickness, with differently adjusted ratio of the thicknesses of the A layers and B layers, wherein: the multilayer coating comprises:• an under multilayer coating portion (100) with an average thickness ratio LTR100 of the average thickness of the A layers (A100) regarding the average thickness of the B layers (B100), and• an upper multilayer coating portion (200) with an average thickness ratio LTR200 of the average thickness of the A layers regarding the average thickness of the B layers,• wherein LTR100 > LTR200.2. Multilayer coating according to claim 1 , characterized in that the multilayer coating is deposited in a substrate surface in such a manner that the under multilayer coating portion (100) is deposited closer to the substrate surface than the upper multilayer coating portion (200).3. Multilayer coating according to claims 2, characterized in that: a. the under multilayer coating portion (100) has average layer thickness ratio between the A layers (A100) and B layers (B100) , LTR100, greater than 1 , i.e. LTR100 > 1 , and b. the upper multilayer coating portion (200) having average layer thickness ratio between the A layers (A200) and B layers (B200), LTR200, LTR200 < 1 .4. Multilayer coating according to any of the previous claims 1 to 3, characterized in that the multilayer coating comprises further coating portions or further coating layers.5. Multilayer coating according to claim 4, characterized in that the multilayer coating comprises an intermediate multilayer coating portion (150) deposited between the under multilayer coating portion (100) and the upper multilayer coating portion (200). 6. Multilayer coating according to claim 5, characterized in that the intermediate multilayer coating portion (150) has an average layer thickness ratio between the A layers and B layers, LTR150, wherein LTR100 > LTR150 > LTR200.
