Experimental and numerical evaluation of the contact fatigue resistance of AlCrN, FexN and AlCrN/FexN coatings on AISI 4140 steel

An experimental-numerical study of the contact fatigue resistance of AlCrN coatings formed on an AISI 4140 steel was performed. Three different coatings were formed: a coating of aluminum chrome nitrides (AlCrN) by a physical vapor deposition process (PVD) with a thickness of 2.2 ± 0.3 μm, a layer o...
