Investigation of (Ti, Al)N Based Coatings Grown by Physical Vapor Deposition

Hard (Ti, Al)N based coatings were deposited by means of physical vapor deposition (PVD) arc ion-platting PLATIT unit on top of the stainless steel AISI 304 and hard metal substrates. The crystal structure, morphology, hardness and adhesion of coating were under investigation. (Ti, Al)N based coatings with the high hardness and smooth surfaces were obtained.
