利用两步工艺结合泥浆烧结法和化学气相反应法在C/C复合材料表面制备了一种新型的SiC?ZrB 2涂层。SiC?ZrB 2涂层由分散的ZrB 2相和连续的SiC相组成，涂层与C/C复合材料基体结合较好。与C/C复合材料相比， SiC?ZrB 2涂层包覆C/C复合材料试样具有更好的抗烧蚀性能。SiO 2?ZrO 2陶瓷层的阻氧作用、气态氧化产物的散热以及ZrO 2的钉扎作用是涂层试样具有良好抗烧蚀性能的主要原因。

A novel SiC?ZrB2 coating was prepared using a two-step technique by slurry-sintering and chemical vapor reaction on carbon/carbon (C/C) composites. The SiC?ZrB2 coating was composed of the scattered ZrB2 phase and the continuous SiC phase. It was observed that a good adhesion was built between the coating and the C/C composites. The SiC?ZrB2 coating samples exhibited a better ablation resistance in comparison with the uncoated C/C composites. The SiO2?ZrO2 barrier layer, the heat dissipation of the gaseous products and the pinning effect of ZrO2 all contributed to the good ablation resistance of the SiC?ZrB2 coated composites.
