摘　　要：目的获取金属铜空间原子氧环境适应性数据,提升材料空间环境适应性设计水平。方法将金属铜样品置于射频源原子氧辐照面积内开展原子氧辐照试验,束流密度为2.5×1016/(cm2·s),最长辐照时间为300 min。研究随辐照时间增加样品表面成分、形貌以及性能的变化。结果原子氧辐照后,金属铜表面变得粗糙,300 min辐照样品出现了氧化层脱落现象;随辐照时间增加,样品质量呈增加趋势,300 min辐照样品质量增加0.035 mg;试验后样品太阳吸收比升高最大值达0.07,光谱反射系数下降;原子氧作用导致金属铜表面疏水性能提高,摩擦磨损性能下降。结论得到了金属铜原子氧环境效应数据,可为航天器空间环境效应防护设计提供技术支撑。Objective To obtain copper properties data in space atomic oxygen （AO） environment and to enhance the design level of material space environment adaptability. Methods AO irradiation test of copper was conducted using a radio-frequency （RF） source AO simulation facility. The flux was 2.5 × 10^16 atoms/cm^2- s and the maximum irradiation time in test was 300 min. The variations in surface composition, surface morphology and properties with the increasing irradiation time were investigated in our study. Results After AO exposure, the sample surface became rough and the copper oxidation layer fell off from the sample surface after 300 min irradiation. The mass and solar absorption ratio of copper increased with the increasing irradiation time, the mass increased by 0.035 mg and the maximum solar absorption increment reached 0.07 after 300 min irradiation. In ＇contrast, the spectrum reflectance decreased with increasing irradiation time. In addition, AO could also lead to the increase of hydrophobic property and decrease of friction and wear property. Conclusion AO effect data of metal copper was obtained, which could provide technical support for the space environment effect protection design of spacecraft.
