在原子氧侵蚀地面模拟设备中对Kapton和利用反应溅射制备的Al_2O_3涂层进行了原子氧暴露实验，并采用XPS和SEM等分析手段对暴露前后试样表面的物理和化学变化进行了研究。结果表明，Kapton式样遭受了严重的侵蚀，质量损失较大；Al_2O_3涂层质量变化很小，对基体提供了良好的保护作用。XPS分析结果表明，Kapton的羰基与原子氧作用时形成CO_2，随后CO_2气体脱附。反应溅射的Al_2O_3涂层是富Al的，初始暴露时由于氧化反应而质量有少许增加，随时间延长，涂层变得完全符合化学计量。 |

The erosion behaviors of Kapton and Al_2O_3 coating have been studied during exposure in atomic oxygen (AO) environment in the ground-based simulation facility. The variations of chemical and physical properties of sample surfaces after exposed to AO fluxes were investigated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The results indicate that Kapton undergoes dramatically degradation, including big mass loss and change of surface morphologies; Al_2O_3 coating has good AO erosion resistance, can provide protection for substrate materials. XPS analysis indicates that the carbonyl group in Kapton reacted with oxygen atoms to generate CO_2 which desorbed from Kapton surface. Prepared Al_2O_3 coating was unstoichiometric with an aluminum sufficiency, its mass increased at the initial stage of AO exposure, this is because of the transformation of substoichiometric to fully stoichiometric due to oxidation. |
