This study investigates the mechanical and tribological properties of monolayer TiN coatings and multilayer TiN/TiCN coatings deposited via direct current magnetron sputtering onto titanium substrates (VT1-0). The coatings were characterized bymicrostructure, nanohardness, elastic modulus, and tribological performance under lubricated friction condi-tions. Scanning electron microscopy (SEM) revealed that the coatings exhibit a uniform microstructure without visible defectsand a typical columnar growth morphology. Nanoindentation tests demonstrated that the multilayer TiN/TiCN coatings possess enhanced hardness (up to 23.5 GPa) and elastic modulus (191 GPa) compared to the monolayer TiN, attributed to interlayer strengthening effects and redistribution of residual stresses. Tribological tests using a ball-on-disk configuration under lubri-cated conditions showed that the multilayer coatings exhibit a significantly lower coefficient of friction (0.10–0.13) and im-proved wear resistance compared to the TiN coating. This behavior is associated with TiCN layers, which reduce interfacial adhesion, promote uniform load distribution, and facilitatesthe formation of a protective tribofilm. The results confirm that the TiN/TiCN multilayer coatings offer superior mechanical and tribological properties, making them promising candidates for engineering components operating under friction and wear conditions.DOI
