Abstract: The effect of complex coating of Sic-Si-ZrSi₂ on the protecting 3-D C/C composite from oxidizing has been studied. Primary coating of Sic was formed by the reaction of Si and 3-D C/C composite substrate. An enhancement coating of Si and ZrSi₂ was provided as a crack sealant and oxidation inhibitor. The SIC-Si-ZrSi₂ coating was able to protect the 3-0 C/C composite from oxidation at 1600°C in air for long period of time.

Keywords: surface coatings; 3-D C/C composites; crack sealant; oxidation inhibitor; silicon carbide; zirconium disilicide.
