摘要
A coating for protecting a carbon fiber or carbon-carbon (C-C) composite component from oxidation comprises a precursor of fluidized glass applied to the component. The precursor-coated component is gradually heated to a temperature of between 250-650 °C to anneal the coating to the component. Alternatively, a thermally matched refractory coating is applied to the C-C component by chemical vapor deposition to create an initial oxidation barrier. The fluidized glass is then applied on top of the refractory coating to enhance the oxidation barrier.
