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 ZrB2-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 ZrB2-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200 μm。涂覆有 ZrB2-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 ZrB2-SiC 复合涂层, ZrB2-SiC 复合涂层使 C/C 复合材料的抗静态烧蚀性能显著提高。 |

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. Results 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 oxidation 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. |
