摘要:
    为了提高碳/碳(C/C)复合材料的抗烧蚀性能，在C/C基体上成功制备了碳化锆(ZrC)高温抗烧蚀涂层。用常压化学气相沉积法，前驱体选用ZrCl4+C3H6+H2+Ar体系。通过调节C3H6的流量，制得3种碳锆原子比的ZrC陶瓷涂层(ZrC10+C, ZrC10, ZrC07)。分析了不同锆碳比ZrC涂层的相组成和形貌差异，研究了锆碳比对ZrC陶瓷涂层的烧蚀性能的影响。结果表明，3种ZrC涂层都可有效提高C/C复合材料的抗烧蚀性能，但由于微观结构特征不同，3种涂层显示不同的烧蚀性能和烧蚀机制。其中，ZrC07涂层试样烧蚀后，表面形成致密的氧化物层，烧蚀性能最佳, 烧蚀240 s后质量烧蚀率和线烧蚀率分别为11×10-4 g/cm2·s和03×10-3 mm/s。
Abstract:
    To improve the anti ablative properties of carbon/carbon (C/C) composites, the controlled preparation of zirconium carbide (ZrC) coatings of superstoichiometric, stoichiometric, and substoichiometric compositions has been achieved utilizing zirconium tetrachloride and propene precursor gases in an atmospheric pressure chemical vapor deposition system. The ablative properties of coated samples were tested in an oxyacetylene torch system. The phase compositions and morphological features of the coatings were investigated pre and post test. The results show that all types of ZrC coatings can protect C/C substrate from ablation.
