A vanadium carbide coating on steel‘s substrates was prepared through B4C reducing V2O5 in molten salt bath. The thickness of VC-coating reached 14-18μm at 920℃ for 6h, and the hardness of VC-coating reached HV2200-HV2400. The sliding wear resistance of the VC-coating is not only 3350 times of that of SCN-coating, but also more excellent than that of other VC-coatings, prepared through aluminum reducing V2O5 or through TD processing. The experimental results indicate that the different VC-coating resistances to wear and corrosion increase with a raise of the free carbon contents in VC-coatings. The continuous service life of a tongue grooves of the high speed cigarette machines, with this VC-coating, reached good results of 140-150days.
