N2 - NbTiAlX, NbTiAl0.5Ny, and NbTiAl0.5N14-CHz coatings were deposited on SKH51 substrates using a radio frequency unbalanced magnetron sputtering system. The NbTiAl0.5Ny coatings prepared with higher nitrogen fluxes (14 sccm) exhibited a denser cross-sectional structure, a higher hardness, a better adhesion, and a lower wear rate than the NbTiAlx coatings. The friction coefficients of the NbTiAl0.5N14-CHz coatings were lower than those of the NbTiAl0.5Ny coatings. Furthermore, the NbTiAl0.5N14-CH12 coating (acetylene flux 12 sccm) had a DLC structure with enhanced adhesion properties and formed a carbon-rich transfer layer on the counterbody surface during sliding. The NbTiAl0.5N14-CH12 coating thus exhibited the best tribological properties among all the coatings.
