中文摘要: 采用 SAPS 法在包埋有 SiC 内涂层的 C/C 复合材料的表面制备了 HfC 抗烧蚀涂层； 通过改变工艺过程中
的电流和电压等参数， 制备了不同的 HfC 涂层试样； 结合 XRD、 SEM、 声发射 - 载荷试验及共聚焦显微镜等表
征手段， 研究了在喷涂电流及电压变化时， 制备出的 HfC 涂层结构、 形貌的变化情况； 通过氧乙炔火焰对不同
涂层的烧蚀性能进行了测试， 并研究了烧蚀后不同涂层形貌和结构的变化。 结果表明， 在喷涂电流为 400 A、 喷
涂电压为 130 V 时制备的涂层综合性能最佳。
Abstract:HfC protective coating was deposited on the surface of SiC-coated C/C composites by SAPS. Different
samples were prepared under the conditions of alternative currents and voltages. Combined with XRD, SEM,
roughness analysis and acoustic emission spectra with load-scratch test, the structure and morphology of the HfC
coatings deposited with different currents and voltages were also studied. The ablation properties of different
coatings were tested by oxyacetylene flame. The changes of the morphology and structure of the different coatings
after ablation were also studied. The results showed that the HfC coating deposited by the current of 400 A and the
voltage of 130 V exhibit the best property
