Abstract

BC_x was prepared by Chemical Vapor Deposition (CVD) process, oxidation behavior of CVD-BC_x and the kinetic parameters of CVD-BC_x oxidation were obtained under water and oxygen environments. The B₂O₃ formed from the oxidation of CVD-BC_x can seal the crack, by using the kinetic parameters of CVD-BC_x consumption and B₂O₃ formation, the self-healing time of the crack can be predicted. The self-healing time of theoretical prediction was verified by the self-healing of the pre-crack in the layered BC_x/SiC structure. The resuts show that the theoretical prediction time is matched the experimental results.
