LEO原子氧剥蚀太阳电池阵 Ag互连材料的试验研究
Experimental study of atomic oxygen erosion of Ag interconnector for solar array in low earth orbit
摘要
Abstract
The atomic oxygen with strong oxidizing capacity is the main component of the space particles in the LEO environment. The solar array exposed to this space will be impacted by a large number of oxygenatoms, and the Ag interconnector, as an atomic oxygen-sensitive material on the solar array, will be eroded . Based on the mechanism of the atomic oxygen erosion of Ag material, the ground simulation environment experiment for different thickness Ag interconnectors is carried out, with the atomic oxygen cumulative flux in an around 400km orbit within a year as the high dose. The experimental results show that the atomic oxygen erodes Ag interconnectors in an "oxidizing-peeling" cycle. The formula for the eroded thickness of Ag interconnectors is derived based on the reaction equation of Ag and atomic oxygen, and the thickness loss rate of Ag interconnectors of different thicknesses is calculated combined with the experimental results. They will provide a technical support for the design of atomic oxygen protection for the solar array in the low earth orbit.关键词
