Notes

“Cutting tools comprise a base body which is made for example from hard metal or carbide metal, cermet, steel or high-speed steel. Frequently a single-layer or multi-layer coating is applied to the base body to increase the service lives or also to improve the cutting properties. That single-layer or multi-layer coating includes for example metallic hard material layers, oxide layers and the like. CVD processes (chemical vapour deposition) and/or PVD processes (physical vapour deposition) are used for applying the layer. A plurality of layers within a coating can be applied exclusively by means of CVD processes, exclusively by means of PVD processes or by a combination of those processes. CVD processes provide substantially stable phases of the desired compounds whereas PVD processes also make it possible to apply metastable phases of compounds.” [Coated Cutting Tools, US Patent 8,491,996 (7/23/2013)]
