Mechanical and Tribological Properties of NbCx Coatings with Different C2H2 Fluxes

Abstract:

NbCx coatings were deposited on SKH51 substrates by RF magnetron sputtering with different acetylene fluxes. The XRD analysis results showed that the crystalline structure of the coatings changed from NbC phase to amorphous phase as the acetylene flux increased. The coating hardness decreased, whereas the adhesion strength increased, with an increasing carbon content. The average friction coefficient of the coatings decreased as the carbon content increased. The coating deposited with an acetylene flux of 8 sccm showed the highest H/E ratio (0.073) and adhesion strength (HF 1) of all the coatings. Consequently, the coating exhibited the best tribological properties, including the lowest friction coefficient and lowest wear depth and wear rate, under normal loads of 2, 5 and 8 N, respectively.
