摘要: 空间太阳电池板可作为空间飞行器的动力源,但由于原子氧在空间太阳电池板银互连片上的腐蚀作用,可能影响空间太阳电池板的有效寿命.因此,在北航流体所设计的原子氧效应地面模拟试验设备中,对空间太阳电池板的银互连片进行了抗原子氧效应地面模拟试验研究.获得了银箔和不同防护镀层材料在原子氧环境中的不同剥蚀结果,这为进行银互连片表面的原子氧防护提供了必要的应用和设计依据.Abstract: Photovoltaic solar array systems are being considered as potential power sources for spacecraft applications. But the AO effect on silver solar cell interconnects would limit the useful life of the solar array. So the experiments were constructed to investigate the interaction between silver interconnects of photovoltaic solar array which are to be used on spacecraft and atomic oxygen environment in the ground-based AO effect simulation facility. After the experiment, different degradation effects of the Ag films and the other plated protective coatings due to atomic oxygen were obtained. This would be of much value in selecting and determining the suitable protective coatings that would keep the silver interconnects from AO degradation while in LEO.
