摘要

To improve the oxidation resistance of C/C composites for long-life service at high temperatures, a SiC/SiC-ZrSi₂ coating with micro-pore was prepared by pack cementation and slurry, respectively. The coating could protect C/C composites for 1194 h at 1773 K in air with a mass gain of 1.42 wt.%. Such good antioxidant property was ascribed to the SiO₂-ceramic inlay structure with the ability of healing and covering the penetrating crack formed during oxidation, which had excellent oxygen diffusion resistance. Besides, the thermal stress was reduced by the micropores and the crack propagation was inhibited by ZrSiO₄ particles.
