Abstract

In this work, the oxidation behavior of C/SiC-Ti₃SiC₂ from 800 to 1300 °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 h at 800 °C. With the oxidation temperature increasing to 1000 °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 h at 1000 and 1200 °C, revealing better oxidation resistance than C/SiC at the temperature range from 1000 to 1200 °C. With the oxidation temperature increasing to 1300 °C, the flexural strength decreases after oxidation of 10 h due to the oxidation of outer carbon fibers.
