Abstract
The invention provides a method for utilizing the inherent oxygen-blocking characteristics of a barrier coating for a carbon-carbon material by penetrating cracked, porous areas of the coating with an oxygen inhibitor. The inhibitor will complex with active carbon-carbon material sites at the base of the cracks. The resulting system provides very effective oxidation protection at intermediate temperatures of approximately 650.degree. C.
