摘要:
采用包埋法、超音速等离子喷涂结合化学气相沉积工艺在C/C复合材料表面制备了SiC/ZrB2-SiC/SiC复合涂层。借助XRD和SEM等测试手段对所制备复合涂层的微观结构进行表征，采用恒温氧化实验及氧乙炔烧蚀实验考察涂层复合材料的高温抗氧化和抗烧蚀性能。结果表明，所制备涂层复合材料在900，1100，1500 ℃均具有较好的高温抗氧化性能，涂层氧乙炔烧蚀60 s后，质量烧蚀率和线烧蚀率分别为-0.05 mg/s和0.56 μm/s。表明所制备的ZrB2-SiC基复合涂层在为C/C复合材料提供良好的抗烧蚀保护的同时，可对材料提供较宽温度范围的抗氧化保护。
Abstract:
The ZrB2-SiC based multilayer coating for carbon/carbon composites was prepared by pack cementation, supersonic plasma spraying and chemical vapor deposition. The microstructures of the as-prepared multi-layer coating were characterized by XRD and SEM. The anti-oxidation and ablation properties of coated composites were investigated by isothermal oxidation test and oxyacetylene flame test. The results show that the as-coated samples can provide good oxidation protection at 900，1100，1500 ℃. After oxyacetylene ablation for 60 s, the mass and linear ablation rates are-0.05 mg/s and 0.56 μm/s, respectively. The prepared ZrB2-SiC based coating can provide good ablation protection for C/C composites, and combined oxidation protection at a wide temperature range.
