摘要

In this work, the oxidation behavior of C/SiC-Ti3SiC2 from 800 to 1300 degrees C has been studied compared with that of C/SiC. C/SiC-Ti3SiC2 shows severe weight loss and low flexural strength after oxidation of 10 hat 800 degrees C. With the oxidation temperature increasing to 1000 degrees C, the coating cracks can be healed by silica and the matrix cracks can be healed by the oxidation product of Ti3SiC2, so the strength retention ratios of C/SiC-Ti3SiC2 reach to above 90% after oxidation of 10 hat 1000 and 1200 degrees C, revealing better oxidation resistance than C/SiC at the temperature range from 1000 to 1200 degrees C. With the oxidation temperature increasing to 1300 degrees C, the flexural strength decreases after oxidation of 10 h due to the oxidation of outer carbon fibers. (C) 2016 Elsevier Ltd.
