| 摘 要： | 目的提高C/C复合材料的抗静态烧蚀性能。方法利用大气等离子喷涂技术在C/C复合材料表面制备ZrB_2-SiC复合涂层,对其进行1500℃的静态烧蚀实验。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)及能谱分析仪(EDS)对涂层的物相成分、微观形貌等进行检测分析。结果采用大气等离子喷涂制备的ZrB_2-SiC涂层是由熔融的粉末粒子紧密堆积而成,呈现典型的层状结构,涂层均匀完整地覆盖于C/C基体表面,厚度约为200μm。涂覆有ZrB_2-SiC复合涂层的C/C复合材料试样在1500℃分别氧化2,3,4 h后,试样依旧保持完整,C/C基体未遭受损伤,试样的质量增加率依次为3.39%,2.95%,4.25%。结论采用大气等离子喷涂技术能够在C/C复合材料表面制备出厚度均匀、结构致密的ZrB_2-SiC复合涂层,ZrB_2-SiC复合涂层使C/C复合材料的抗静态烧蚀性能显著提高。

| Abstract: | Object To improve the static ablation-resistance of C/C composites.Methods The ZrB2-SiC composite coatings were deposited on C/C composites by atmospheric plasma spraying (APS). Oxidation experiments were carried out at 1500℃on the ZrB2-SiC coated C/C composites. After that, microstructures of the coatings were analyzed by XRD, SEM and EDS.Re-sults The homogeneous ZrB2-SiC coatings prepared on the surface of C/C composites by APS showed typical layer structure, and the coatings were composed of molted powder particles with close packing. The thickness was about 200 μm. After oxida-tion at 1500℃ for 2 h, 3 h and 4 h, the coated specimen still kept intact and did not suffer any injury, the weight increase of C/C specimen was 3.39%, 2.95% and 4.25%, respectively.Conclusion The homogeneous and integrated ZrB2-SiC composite coatings could be fabricated on the surface of C/C composites by atmospheric plasma spraying (APS), and ZrB2-SiC composite coatings could effectively improve the oxidation-resistance of C/C composites. |
