Grain Vanadium Carbide Powder For Cermet

Application:

Vanadium carbide is used in WC-Ni cemented carbide, in which a small amount of vanadium carbide can effectively reduce the Curie point of the alloy, so that the alloy is changed from ferromagnetic to paramagnetic at room temperature. The addition of VC can reduce the saturation magnetization, remanent magnetic force, coercive magnetic force, magnetic energy product, magnetic permeability and Curie temperature of WC-10%Ni cemented carbide, and produce a non-magnetic alloy. The mechanism of action is: the solid solution of VC in the bonding phase increases the atomic distance a of the Ni lattice, so that the ratio of the radius r of the unfilled electron layer of a and Ni increases, and the alloy changes from magnetic to non-magnetic.
