Investigation of Adhesion Behaviour of Different Underlayered DLC Coated Cold Forming Tool Steel

Mono- and multilayer coatings can be suitable alternatives to traditional bulk materials due their favorable mechanical properties. Thanks the ever-evolving coating technology process, there are a wide variety of types today, such as soft, hard, or super-hard that made with single coatings.
 Adhesion damage is especially important for coated tools, where reduce tool life result in deterioration surface quality product. The were characterized by Calotest layer thickness measurement, AFM assisted roughness measurement microhardness test. adhesion test different underlayered (TiBN, CrN TiAlN) DLC Böhler K100 forming steel designed Mercedes (Rockwell C Test), which frequently used classify layers, complemented instrumented scratch
