Abstract

A model for the deposition of alumina and titanium carbide within a ceramic fiber bundle from the chemical reactions has been examined in this paper. The model considers vapor diffusion, chemical reaction on the inner surface of the capillary, deposition film growth, porosity, and effects of reactants composition at various reactor temperature and pressure. Binary, multicomponent diffusion and Knudsen diffusion have been taken into account for the different stages of the CVI process. Furthermore, both diffusion controlled and reaction controlled processes have been examined in order to determine the dominating process in chemical vapor infiltration.
