低地球轨道环境对材料的影响

Low Earth Orbit Environmental Effects on Materials

综述了原子氧、空间辐射、热循环、高真空、微流星和空间碎片等低地球轨道环境因素对材料性能的影响 ;从地面模拟实验、材料研制与防护涂层的开发等方面提出了急需解决的问题 ,为空间站。

Stability of materials in low Earth orbit environment (LEO) is one of the most important factors that were concerned for the selection of spacecraft materials.The effects of LEO environment,including those of atomic oxygen,space radiation,thermal cycling,vacuum,micrometeroids and space debris on materials are described.Future research directions,such as ground based simulation tests,development of materials and protective coatings are presented.
