Abstract
Easy oxidation of carbon limits applications of carbon-carbon composites in an oxygen-containing environment. In this study, a two-layer SiC coating was prepared on carbon-carbon composites by a Spark plasma sintering technology at 1350 ° C for 1 min. The coating was mainly composed of β -SiC and Si and well bonded with the substrate. The double SiC coating could effectively protect the C/C composites from oxidation at 1600 ° C for 120 h, and the corresponding weight loss was only 2.62%.
