Abstract
Coated article, e.g., a brake disc, comprising a carbon-carbon composite component or a carbon-carbon-silicon carbide component coated at least with a phosphorus-containing antioxidant undercoating, the undercoating being covered by a silicon carbide particle-containing overcoating of alkali or alkaline earth metal silicate, pH modifier, and silicon carbide particles. Also, method of protecting a carbon-carbon composite brake disc or a carbon-carbon-silicon carbide composite brake disc against oxidation, by: coating the composite brake disc with a first phosphoric acid-based penetrant system; curing the penetrant coating at a temperature of 200° C. or above to form a first coating on the composite brake disc; applying the ceramic coating composition of claimover the first coating and curing the ceramic coating at a temperature below 200° C. to form a second coating on the composite brake disc; and optionally coating the coated composite brake disc so obtained with a second phosphoric acid-based penetrant system; and curing the penetrant coating at a temperature of 200° C. or above to form a third coating on the composite brake disc.
