Formation of diffusion silicide layers on Fe−C alloys

  • 17 Accesses

Conclusions

  1. 1.

    During siliciding at the diffusion layer-base boundary there is formation of low-melting point eutectic providing an anomalously high rate of impregnating element diffusion.

  2. 2.

    An increase in temperature and carbon content in Fe−C alloys promotes development of an accelerated effect for silicon diffusion.

  3. 3.

    Determination of the mechanism for liquid-phase diffusion in Fe−C alloys makes it possible to develop controlled processes for obtaining diffusion layers of considerable thickness.
