| 摘 要： | 为探索大气中的红外干扰材料可否应用于外层空间，利用原子氧效应地面模拟装置对铜粉和石墨粉两种红外干扰材料样品进行了原子氧暴露实验，并对样品进行了质量分析、XRD分析和红外透过率测试．结果表明，原子氧累积通量达到5．0×10^19cm^-2时，铜粉样品质量增加0．004mg·cm^-2，石墨粉样品质量损失0．117mg·cm^-2；原子氧暴露后，铜粉对3—5μm与8—12μm红外质量消光系数由3．64m^2·g^-1与2．74m^2·g^-1变为3．14m^2·g^-1与2．65m^2·g^-1，消光能力降低；石墨粉对3—5μm和8-12μm红外的质量消光系数由6．54m^2．g^-1和5．78m^2．g^-1减小为2．38m^2·g^-1和2．27m^2．g^-1，消光能力明显减弱．

| Abstract: | Brass and graphite particles are effective Infrared Ray(IR)interference materials which were usually used in conventional passive jamming technology,but Atomic Oxygen(AO)may corrode them and weaken their performance if they were used in outer-space.For analyzing the effect of AO to IR interference materials and exploring whether the IR interference materials can be used in outerspace, an experiment was conducted to investigate the AO effects.The mass,X-ray diffraction and IR transmittance of the sample were... |
