| 目的 研究低轨环境对KS-B高吸收高发射无机热控涂层(简称KS-B涂层)性能的影响。方法 对KS-B涂层分别进行总剂量为3.9×1022 atoms/cm2的原子氧辐照、剂量为5000 ESH的真空-紫外辐照、总注量为9.30×1011 p/cm2的真空-质子及总注量为1.108×1014 e/cm2的真空-电子综合辐照试验，分析空间模拟辐照环境中KS-B涂层太阳吸收比(αS)、半球发射率(εH)、表面形貌、表面组分含量、质量损失率等性能的变化规律，研究KS-B涂层的耐空间环境稳定性。结果 原子氧暴露后，KS-B涂层太阳吸收比增加0.003，半球发射率增加0.004;原子氧辐照后，KS-B涂层表面形貌出现了一定程度的糙化，表面Si、O元素含量下降。初始暴露时，KS-B涂层质量损失率逐渐提高，最终质量损失率为0.96%。真空-紫外辐照后，KS-B涂层太阳吸收比增加0.003，半球发射率无变化。真空-质子及真空-电子辐照前后，KS-B涂层太阳吸收比增加0.001，半球发射率无变化。结论 经历原子氧、真空-紫外、真空-质子及真空-电子模拟辐照后，KS-B涂层的太阳吸收比及半球发射率变化较小，具有较好的耐空间辐照性能，可以满足空间站等低轨航天器的长寿命服役需求。 |

| The work aims to study effect of low earth orbit environment on the performance of high absorption and high emissivity inorganic thermal control coating (KS-B coating). The KS-B coatings were irradiated with atomic oxygen dose of 3.9×1022 atoms/cm2, vacuum-ultraviolet dose of 5000ESH, vacuum-proton radiation flux of 9.3×1011 p/cm2, vacuum-electron radiation flux of 1.108×1014 e/cm2. By analyzing the changes of coating solar absorption ratio (αS), hemispheric emissivity (εH), morphology, composition and mass loss rate before and after the space irradiation tests, the stability of KS-B coatings in simulated enviroments was studied. After AO exposure, the αS of the KS-B coating increased by 0.003, and the εH increased by 0.004; the coating surface became roughing; silicon and oxygen content on the coating surface decreased slightly. At the initial exposure, the coatings’ mass loss rate gradually increased. The final mass loss rate was 0.96%. After VUV irradiation, the αS of the KS-B coatings increased by 0.003, and the εH did not change. After vacuum proton and electron irradiation, the αS of the KS-B coatings increased by 0.001, and the εH did not change. After AO, VUV, proton and electron simulated irradiation tests, the smallΔαS and ΔεH change indicated that the coating has stable structural properties, which can meet long-life service requirements of low orbit spacecraft such as the space station. |
