Abstract

Modification of SiC coating was carried out with B and BC_x prepared by chemical vapor deposition (CVD), SiC/B/SiC and SiC/BC_x/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°C. The results show that the B₂O₃ glass produced by oxidation of B or BC_x 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/BC_x/SiC-C/SiC composites have lower weight loss during the oxidation and higher strength retention after oxidized for 10 h.
