原子氧对金属Ag及其表面TiO2-有机硅热控涂层的侵蚀
OXYGEN-ATOM EROSION TO Ag AND TiO2-SILOXANE THERMAL CONTROL COATINGS ON Ag SURFACE
【摘要】 在微波电离型原子氧(AO)源地面模拟设备中对空间材料Ag及TiO2-有机硅热控涂层进行原子氧剥蚀效应试验.用LAMBDA-9分光度计、光电子能谱(XPS)、红外光谱(FTIR)和扫描电镜(SEM)对模拟原子氧(AO)环境中的Ag及其涂覆有机硅热控涂层的表面所发生的侵蚀与防护作用进行了表征.结果表明, AO对Ag表现了较严重的侵蚀作用,而所施用的TiO2-有机硅热控涂层的表面形貌则变化甚少,该涂层对AO辐照有较强的防护效果、较好的空间稳定性(AO辐照前后Aα≈0)和热控性能.
【Abstract】 Silver, as a material applied solar cell interconnects, is susceptible to atomic oxygen (AO) erosion. Exposure experiment by ground-based simulation facility indicates that Ag undergoes weight loss and surface degradation. A siloxane thermal control coating on silver with low sunlight-absorption, was developed for anti-AO erosion. The surfaces of the coatings with and without exposure to AO were analyzed with SEM, FTIR, XPS and LAMBDA-9 spectrophotometer. The results indicate that the proposed siloxane thermal control coating has excellent properties for anti-AO effects and good stablility for space environment.
【Key words】 Ag; atomic oxygen; erosion; TiO2-siloxane thermal control coating;
