· Co2N

Co₂N is a cobalt nitride intermetallic compound belonging to the family of transition metal nitrides, which are ceramic-like materials combining metallic and covalent bonding characteristics. This material is primarily of research and emerging industrial interest for applications requiring high hardness, wear resistance, and thermal stability; cobalt nitrides are being investigated as alternatives to traditional hard coatings and tool materials, particularly where corrosion resistance and cost-effectiveness relative to established nitride systems (TiN, CrN) are considerations.
