Abstract:
1. A coated article comprising a carbon-carbon composite component having a density in the range of from about 1.6 g/cm 3 through 2.0 g/cm 3 , said carbon-carbon composite component configured as an aircraft landing system brake disc and being covered by a phosphorus-containing antioxidant undercoating having a thickness of approximately 1-10 mil annealed to said carbon-carbon composite component at a temperature in the range of 250-900° C., said undercoating being covered by a silicon carbide particle-containing overcoating having a thickness of approximately 1-10 mil dried onto said undercoating at ambient temperature for at least one hour, said overcoating being made from 60-80 wt-% water-miscible silicate-based binder solution, up to 20 wt-% alkali metal hydroxide, and 10-30 wt-% silicon carbide, wherein the silicon carbide component of said silicon carbide particle-containing overcoating consists of silicon carbide particles having particle sizes ranging from 0.05 to 0.5 microns.
