摘要

To increase the oxidation resistance of carbon/carbon (C/C) composites at high temperature, it was modified by ZrB₂-SiC ceramics with precursor infiltration and pyrolysis process, then SiC coating was prepared on the modified composites by pack cementation. The results show that the SiC coating prepared with Si/C weight ratio of 6:0.5 has better oxidation resistance, It can effectively protect C/C composites for 100h at 1773K with the weight gain per unit area of 7.75gcm^-2. The good oxidation resistance of the coated composites is attributed to the formation of dense SiO₂ glass during the oxidation test.
