摘要：

Modification of Sic coating was carried out with B and BCx prepared by chemical vapor deposition(CVD), SiC/B/SiC and SiC/BCx/SiC multi-layer self-healing coatings were prepared on a two-dimensional C/SiC composite. The surface and cross section morphologies of the multi-layer coatings were analyzed by SEM. Oxidation were carried out in static air at 700 degrees C. The results show that the B2O3 glass produced by oxidation of B or BCx can seal the cracks existed in the coating well, the kinetics of oxidation is controlled by diffusion of oxygen through the micro-cracks and B2O3 glass layer; SiC/BCx/SiC-C/SiC composites have lower weight loss during the oxidation and higher strength retention after oxidized for 10h.
