中文摘要:
      目的 研究空间辐照环境对SCB-1消杂光热控涂层性能的影响。方法 采用剂量为5000 ESH的真空-紫外辐照、总注量为2.5×1015 p/cm2的真空-质子辐照、总注量为2.5×1016 e/cm2的真空-电子辐照以及2.0× 1021atoms/cm2的原子氧辐照,分别对SCB-1型消杂光热控涂层进行模拟空间环境试验,分析空间辐照试验前后涂层太阳吸收比αS与半球发射率εH的变化,并通过X-射线光电子能谱(XPS)检测涂层表面元素状态变化,从而判断SCB-1涂层耐空间各项辐照因素的稳定性。结果 经真空-紫外辐照后,SCB-1涂层全波段αS下降了0.007~0.009,400~1100 nm αS下降了0.008~0.010;经原子氧作用后,SCB-1涂层全波段与400~1100 nm αS均下降了0.006~0.009;经真空-质子辐照后,全波段αS下降了0.004~0.005,400~1100 nm αS下降了0.005;经真空-电子辐照后,吸收比无明显变化。以上辐照过程中,SCB-1涂层的半球辐射率均无明显变化。结论 经历空间模拟辐照试验,SCB-1消杂光热控涂层展现出了极佳的抗空间辐照稳定性,可以满足后续GEO、LEO等航天器的长寿命设计使用需求。
英文摘要:
      The work aims to study the effects of space irradiation environment on the properties of SCB-1 stray light coatings. Simulated space environment test of SCB-1 stray light coatings was conducted with vacuum-ultraviolet dose of 5000 ESH, vacuum-proton radiation flux of 2.5×1015 p/cm2, vacuum-electron radiation flux of 2.5×1016 e/cm2 and atomic oxygen dose of 2.0×1021 atoms/cm2. The changes in the solar absorptionαS and hemispheric emissivityεH of the coatings before and after the space irradiation test were analyzed. The state changes of surface elements of the coatings were detected by X-ray photoelectron spectroscopy (XPS) to judge the stavility of SCB-1 coatings under dfferent radiation factors.After vacuum-ultraviolet irradiation, the solar absorption of the SCB-1 coatings in the full-wave band decreased by 0.007~0.009, and the solar absorption in 400-1100 nm decreased by 0.008~0.01. After atomic oxygen radiation, the solar absorption in both the full-wave band and 400~1100 nm decreased by 0.006~0.009. After vacuum-proton radiation, the solar absorption in the full-wave band and 400~1100 nm decreased by 0.004~0.005 and 0.005 respectively. After vacuum-electron radiation, no significant change was found in the absorption. There was no significant change in the hemispheric emissivity of SCB-1 coatings during the above irradiation processes. The simulated space irradiation experiment demonstrates that the SCB-1 stray light coatings have excellent stability against space irradiation. They can meet the needs on design of long service life spacecraft such as LEO and GEO.
