· CoN

Cobalt nitride (CoN) is a hard ceramic compound combining cobalt metal with nitrogen, belonging to the transition metal nitride family. It is primarily investigated for wear-resistant coatings and hard surface applications, where its high hardness and chemical stability make it attractive as an alternative to traditional hard coatings like TiN or CrN. Industrial interest centers on cutting tools, wear-protective coatings for mechanical components, and high-temperature applications, though CoN remains largely in the research and development phase compared to more established nitride coatings.
