Technical Information


  1. 1.

    The process of heating ammonia in the furnace for nitriding is practically inertialess.

  2. 2.

    Analytical expressions for the dynamic characteristic of the dissociation of ammonia during nitriding were obtained in relation to its input in the form of a nonlinear differential equation of the first kind.
