Abstract
The effect of temperature on oxidation behavior of 3-dimensional C/SiC composites coated with SiC and a-BCx coatings was investigated. Below 1000°C, C/SiC composites with SiC coating (sample SSS) showed low residual strength, while the composites with a-BCx coating (sample BBB) and the composites with a-BCx/a-BCx/SiC 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.
