Refractory silicon-based barrier coatings are a promising approach for improving the environmental durability of C/C composites in severe environment such as high temperature oxidation atmosphere. The oxidation resistance of C/C composites coated with a newly developed multi-layer C-Si(composite with SiC fiber)-SiC(CVI)was investigated. The C-Si interleaving layer between C/C composite substrate and SiC coating is expected to act as a buffer layer that reduced the thermal stress caused by the mismatching of the coefficient of thermal expansions(CTEs)between the substrate and the coating. The multi-layer coated 3-D C/C sample exhibited significantly improved oxidation resistance owing to change the crack propagation(such as the crack termination and deflection)of the CVD-SiC coating when compared to that without C-Si interleaf. The coated specimens were examined by oxidation test at 1700℃ in the methane-fired exhaust gas.
