Vanadium Nitride (VN) is a ceramic-like interstitial compound that combines vanadium metal with nitrogen, forming a hard refractory material with metallic electrical conductivity. It is used in cutting tool coatings, wear-resistant applications, and high-temperature structural components where hardness and thermal stability are critical. Engineers select VN coatings for machining applications and industrial tooling because of its superior hardness and resistance to thermal shock compared to conventional tool steels, though it is typically applied as a thin coating rather than used as a bulk material.
