Abstract

Modification of SiC coating was carried out with B and BCx 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℃. 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/BC x/SiC-C/SiC composites have lower weight loss during the oxidation
and higher strength retention after oxidized for 10h.
