摘要 空间飞行器是人类探索、开发和利用外太空的载体,飞行器材料由于在低地球轨道空间中受到各种侵蚀作用而性能退化,其中高能量的原子氧(AO)是导致空间飞行器材料产生失效的最主要的环境因素。综述了空间原子氧对典型空间材料的侵蚀行为以及各类抗原子氧侵蚀的防护涂层技术,重点介绍了新型石墨烯二维材料及其复合改性涂层对原子氧侵蚀的防护性能,以期为抗原子氧侵蚀防护涂层的开发提供技术参考。 Space vehicles are important carriers for humans to explore, develop and utilize outer space. In low Earth orbit(LEO) space, the performance of aircraft materials is degraded due to various erosion-corrosion effects. Among them, high energy atomic oxygen(AO) is the most important environmental factor responsible for the failure of spacecraft materials. The AO erosion-corrosion behavior of space atomic oxygen to typical space materials and various AO-resistant coating technologies are reviewed. The protective properties of a novel graphene two-dimensional material and its composite modified coatings against atomic oxygen erosion-corrosion are introduced in detail in order to provide technical reference for the development of AO-resistant coatings.
