Ta4Co2N
metal· JVASP-120452· Ta4Co2N
Ta₄Co₂N is a transition metal nitride compound combining tantalum and cobalt in a nitride matrix, representing an intermetallic/ceramic hybrid material class. This is primarily a research and development compound studied for its potential hardness, thermal stability, and wear resistance; it belongs to the family of refractory metal nitrides being explored to replace or supplement conventional hard coatings and high-temperature alloys. While not yet established in high-volume industrial production, materials in this chemical family show promise in demanding applications requiring resistance to extreme temperatures, mechanical wear, and oxidation.
