Vanadium carbide thin films were grown over M2 steel substrates using RF Magnetron reactive sputtering and a 2-inch diameter target (99.99 %). CH4 methane flow varied from 0.5 to 3.0 sccm. in the mixture of Ar/CH4. X Ray diffraction analysis show that the films are predominantly crystalline and exhibit two phases of the VC binary system. The XRD diffractograms show a predominant crystallographic orientation (111) due to the NaCl-type structure substoichiometric VC phase. The intensity of this peak increases with the concentration of methane. Peaks associated to the -V2C phase can be observed in the diffractograms which revealed high concentrations of methane. The morphology of the surface layers was analyzed by AFM. Tribological properties such as the friction and adhesion coefficient were studied using the pin-on diskand-scratch test techniques. The friction coefficient decreases in a scale from 0.8 to 0.3 and the critical load varied between 30 N to 50 N when the methane concentration was increased. The thin films’ hardness was measured by nano-indentation technique and the values were between 8 and 20 Gpa.
