摘要

To protect carbon/carbon (C/C) composites from oxidation at high temperature, a LaB₆ modified MoSi₂ outer coating was produced on SiC coated C/C composites by pack cementation technique. The phase composition, microstructure and oxidation protective ability of the LaB ₆-MoSi₂/SiC ceramic coatings were investigated. Results show that the LaB₆-MoSi₂/SiC coating possesses dense and crack-free microstructure and can effectively protect C/C composites from oxidation for 750 h at 1773 K in air. The weight loss of the as-received coated C/C composites is only 0.108% after oxidation process.
