· HfWN3

HfWN3 is a refractory metal nitride compound combining hafnium and tungsten with nitrogen, belonging to the family of transition metal nitrides known for extreme hardness and thermal stability. This material is primarily of research and developmental interest for ultra-high-temperature applications and hard coatings, where its combination of metallic and ceramic properties offers potential advantages over traditional carbides and nitrides in aerospace, cutting tool, and wear-resistant coating applications.
