为了提高C/E复合材料的导电性及耐空间环境的能力,应用电弧离子镀技术在C/E复合材料表面沉积了A l膜,研究了地面模拟原子氧环境对C/E复合材料表面镀A l前后的侵蚀、质损及A l膜的附着力、导电性的影响。通过XRD、SEM、FT-IR、万能拉伸测试仪、FZ-82数字式四探针测试仪等测试分析样品。结果表明:电弧离子镀A l膜微米级以上颗粒较多,但分布均匀,膜层致密,附着力达2 N/mm2以上;原子氧对C/E复合材料侵蚀明显,镀铝后具有明显的防护作用;原子氧侵蚀后的A l膜电阻率有所上升,但还是有较好的导电性;辐照后的A l膜附着力比辐照前反而增加,其机理尚待进一步研究。
In order to improve the conductivity of C / E composites and space-resistant environment, arc ion plating technique was used to deposit Al film on the surface of C / E composites. The effect of ground simulated atomic oxygen environment on the surface of C / E composites A l before and after the erosion, damage and A l membrane adhesion, conductivity. The samples were analyzed by XRD, SEM, FT-IR, universal tensile tester, FZ-82 digital four-probe tester. The results show that the Al2O3 particles on the arc ion plating are more than those on the micron scale, but the distribution is uniform and the film is dense with an adhesion of more than 2 N / mm2. The atomic oxygen has obvious corrosion on the C / E composites, After the atomic oxygen attack, the resistivity of Al film is increased, but it still has better conductivity. The adhesion of Al film after irradiation is increased compared with that before irradiation, and its mechanism remains to be further studied.
