TiC–Cr3C2–WC–NiCr–Mo–C Cermet Plasma Coatings

Two bulk cermets TiC–WC–Cr3C2–(Ni80Cr20)–Mo–2.8C after liquid-phase sintering at 1400°C for 1 h were used to manufacture powders for plasma spraying of coatings. The cermets were fabricated at a limited time of mechanical alloying at the mixing stage. Plasma coatings were sprayed on a setup with a nozzle attached to a plasmatron for local protection of the sprayed particles from the air atmosphere. The WC–Cr3C2–C content in the cermets provided...
