The properties of CrN, AlCrN and AlTiN coatings deposited on cemented carbide substrates by a multiple-arc Physical Vapour Deposition (PVD) technique were evaluated by cyclic impact wear and micro-scale abrasion testing. In the impact wear test, a 6mm diameter tungsten carbide ball was used as the i...
