空間原子氧環(huán)境對常用熱控涂層的影響

The effects of atomic oxygen on the thermal control coatings in common use

摘要: 空間原子氧（AO）是影響低地球軌道（LEO）航天器在軌性能的主要空間環(huán)境因素之一，其強氧化性能夠對熱控涂層和組件造成危害。文章分析了空間AO及相關綜合環(huán)境對白漆、黑漆、有色有機漆、薄膜、織物、二次表面鏡等各類常用熱控涂層在LEO長期使用時可能引起的環(huán)境效應和危害，提出了相關使用建議，以期為今后我國以空間站為代表的LEO長壽命航天器論證及研制提供技術參考。

Abstract: The atomic oxygen is one of the most important space environments in the LEO space, which could damage the thermal control materials and the components of the spacecraft due to its huge erosion effect. This paper studies the atomic oxygen and its effect on the LEO thermal control coatings including white paint, black paint, organic colored paint, polymer film, coated fabric, and second surface mirror, and advances some reasonable proposals for the long term LEO mission design such as for the space station of China.
