文章综述了低地球轨道(LEO)中原子氧(AO)环境对航天材料影响的研究现状。首先介绍AO对材料的危害及作用机制等。然后重点阐述了国内外学者关于AO与Al、Ag、Cu、Ni等金属材料以及半导体材料作用的研究成果。最后总结了AO的防护方法,及其对不同材料抗AO侵蚀能力的改善结果。 This paper summarizes the research status of the impact of atomic oxygen (AO) environment on aerospace materials in Low Earth Orbit (LEO). First of all, the harm of AO to materials and mechanism of action are introduced. Then the research results of domestic and foreign scholars on the effects of AO, Al, Ag, Cu, Ni and other metal materials and semiconductor materials are mainly described. Finally, the protection methods of AO are summarized, and the results of improving the AO erosion resistance of different materials are summarized.
