Abstract
AbstractCoating layers are usually applied on different manufacturing tools to improve their wear resistance and surface properties of the final parts. In this work, fracture and damage behavior of hard coatings such as (Cr,Al)N is studied. The coatings are produced by means of direct current magnetron sputtering (dcMS) and high power pulsed magnetron sputtering (HPPMS) method. The fracture properties of the coating are measured by investigating the force‐displacement curve obtained from a bending test [1]. The cohesive zone element parameters are then fitted to the experimental results to simulate the same behavior. The intergranular fracture within the coating system can then be modeled by employing the cohesive zone (CZ) regions at grain boundaries [2]. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
