It has been found that the vanadium compounds have a coefficient of
friction lower than the control samples HSS, the lowest values were
determined for the vanadium carbide (μ = 0.5-0.56). The wear mechanism
changes from a cohesive wear, in the case of vanadium carbide monolayer, to
an abrasive wear mechanism in the case of vanadium multilayer structures.
Although vanadium carbide has the highest microhardness, its wear resistance
is not so good, but when the VN is reinforced with the VC layer, the wear
resistance increases significantly
