In this paper, spark plasma sintering (SPS) was used to pre- pare SiC bonding layer on C/C composites. The results show that a dense SiC layer could be ob- tained at 1200˚C~1400˚C. SiC bonding layer prepared at 1300˚C for 1 min is crack-free, well bonded with the substrate, and the particles size are 5~10 µm. The SiC layer could protect the C/C composites from oxidation at 1400˚Ceffectively.
