· CoIrN3

CoIrN3 is an intermetallic compound combining cobalt, iridium, and nitrogen, representing a research-phase material in the family of high-entropy and refractory metal nitrides. This composition falls within experimental metallurgy aimed at developing materials with enhanced hardness, thermal stability, and wear resistance for demanding aerospace and tooling environments. While not yet widely deployed in production, materials in this chemical family are being investigated as potential alternatives to conventional carbide and nitride coatings where extreme hardness and oxidation resistance are required.
