采用两步法在碳/碳(C/C)复合材料表面制备了ZrB2-SiC-Si/B改性碳化硅涂层。涂层能有效地保护C/C复合材料免受氧化和烧蚀。涂层抗氧化性的提高归功于多层涂层的自封接性能。致密的玻璃氧化层可以承受高达2573K的高温，并有效地保护C/C复合材料免受烧蚀。
ZrB2–SiC–Si/B-modified SiC coating was prepared on the surface of carbon/carbon (C/C) composites by two-step pack cementation. The coating could efficiently provide protection for C/C composites from oxidation and ablation. The improvement of oxidation resistance was attributed to the self-sealing property of the multilayer coating. A dense glassy oxide layer could afford the high temperature up to 2573K and efficiently protect C/C composites from ablation.
