This study investigates the deposition of TiN coatings on two stainless steels that have been plasma nitrided before coating deposition. The steels were plasma nitrided under several conditions, producing compound layers and diffusion zones of varying thickness. Subsequently, TiN coatings were produced by electron beam P VD on the nitrided steel substrates. The hardness, microstructure, and phase distribution of the surface regions of the nitrided steels with TiN coatings were investigated by optical metallography, micro hardness measurements, scratch adhesion tests, Auger electron spectroscopy, and X -ray diffraction.
