The effect of temperature on oxidation behavior of 3‐dimensional C/SiC composites coated with S i C and a‐ BC x coatings was investigated. Below 1000°C, C / S i C composites with S i C coating (sample SSS ) showed low residual strength, while the composites with a‐ BC x coating (sample BBB ) and the composites with a‐ BC x /a‐ BC x / S i C coatings (sample BBS ) showed high residual strength. Above 1000°C, samples SSS and BBS showed high residual strength, while sample BBB showed the opposite results. Sample BBS presented better oxidation resistance during 700–1200°C. The oxidation temperature made an effect on self‐sealing mode of sample BBS .
