Vanadium carbide is a kind of metallurgical and chemical industry commonly used materials, the structure for the VC, for the face-centered cubic NaCl-type crystal structure, lattice constant a = 0.4165 nm. The main components are C and V, in addition to a small amount of Mo, Ni, Fe and so on. In accordance with the requirements of the chemical composition of vanadium carbide, the carbonation rate of 99%, allowing a small amount of impurities.
Vanadium carbide can be widely used in metallurgy, electronics, catalyst and other fields. It can be used in structural steel, tool steel, pipeline steel, steel bar, general engineering and cast iron, because it has some special properties. It has been shown that the addition of vanadium carbide to steel can improve the wear resistance, corrosion resistance, toughness, strength, ductility, hardness and thermal fatigue resistance of steel, and make the steel have good weldability Performance, and can play to eliminate the role of extension and other inclusions.
Vanadium carbide can be used as superfine cemented carbide grain inhibitor, adding a small amount of VC can significantly improve the hardness and fracture toughness of the matrix alloy to prevent WC grain growth in cemented carbide; addition of carbide can also make carbide life Increased by 20%.
Vanadium carbide in high-temperature coatings, and carbon source synthesis of diamonds and other industries have also been widely used.
