【 摘 要 】

This paper presents the study of the influence of a substrate structure on the adhesion behavior of monolayer coatings TiN and multilayer coatings TiAl3/ TiAlN deposited by vacuum arc plasma. Martensitic steel with a coarse-grained (CG) and ultrafine-grained (UFG) structure was used for samples. The samples were subjected to ion nitriding in a glow discharge before coating deposition. Adhesion of the coatings was examined with CSM ScratchTEST. For samples with different structures, critical load was defined at which microcracks are formed in the coatings.
