There is continued interest in the use of carbon/carbon for a variety of structural applications because of the excellent strength retention exhibited by this composite at high temperatures. However, the principal performance limiting issue, which is oxidation protection, has yet to be solved. Coating development efforts have been extensively pursued and the factors that limit the effectiveness of oxidation protection systems are identified. This paper reviews the temperature dependency of several important criteria such as the limitations imposed by oxygen permeability, and the kinetics of oxidation for candidate coating materials. The influence of active/passive transition, mass loss by evaporation, and thermochemical stability are also included.
