Behavior of zirconium and niobium carbides in plasma

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    Plasma deposition of zirconium, and niobium carbides should be performed in a gaseous medium with an oxygen percentage lower than 0.3% by volume, using particles with a mean size of 30 μm.

  2. 2.

    For niobium carbide, the maximum attainable composition in plasma vaporized coating is NbC0.8.

  3. 3.

    For zirconium carbide, the maximum composition achieved in our experiments was ZrC0.9; however, there is no obstacle in principle to achieving a ZrC composition.

  4. 4.

    The percentage of free carbon in the vaporized coating of carbides is reduced by about one half.
