在微波电离型原子氧（AO）源地面模拟设备中对空间材料Kapton及SiO2-K2SiO3无机-有机复合涂层进行原子氧剥蚀效应试验。用扫描电镜(SEM)、光电子能谱(XPS)、红外光谱(FT-IR)、X射线衍射光谱（XRD）和LAMBDA-9分光光度计，对在模拟原子氧(AO)环境中Kapton及在其表面涂覆的涂层所发生的侵蚀与防护作用进行了表征研究。AO对Kapton表现了较严重的侵蚀作用，表面呈现粗糙，失去原有光滑和透明。而施加的SiO2-K2SiO3涂层，经AO辐照后，表面却变化甚少。实验表明，该涂层对AO辐照有较强的防护效果，有较好的空间稳定性，能阻止AO对基材的侵蚀。
Atomic oxygen erosion of spacecraft materials and protection by coatings were studied in the ground-based simulation facilities. The corrosion morphologies and products were characterized by several physical techniques, including scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Silicon dioxide- potassium silicate organic-inorganic composite coatings due to higher conductivity improved resistance to high temperature and thermal cycling. The results indicated that Kapton is susceptible to AO erosion and undergoes mass loss and surface degradation. SiO2-K2SiO3 coatings have excellent properties for anti-AO effects and good stability for space environment.
