样品温度对原子氧环境下ITO/Kapton/Al涂层性能变化的影响

Influences of sample temperature on the property of ITO/Kapton/Al in atomic oxygen environment

  • 摘要: 文章利用原子氧环境地面模拟设备对航天器用材料ITO/Kapton/Al开展了原子氧环境试验研究。研究中选择的原子氧积分通量为9.1×1019 atoms/cm2,试验真空度为10-2 Pa量级,样品温度分别选取为25℃、70℃、100℃、120℃和150℃,研究样品温度对原子氧环境模拟试验可能造成的影响。试验后利用高精度微量电子天平对样品进行了质量损失测试并计算了材料的反应率,利用TEMP 2000A便携热发射率测试仪和LPSR 300便携光谱太阳吸收率测试仪分别对样品的发射率和太阳吸收比进行了测试。通过试验及分析发现:ITO膜对基底材料的保护较好,材料在试验后质量损失较少,原子氧反应率较低;样品温度的变化对ITO/Kapton/Al材料的质量损失影响较小,但对材料的热物理性质影响较大。

     

    Abstract: This paper studies the atomic oxygen erosion effect on ITO/Kapton/Al by using the ground facility. Samples were exposed to a fluence of 9.1×1019 atoms/cm2 under 10-2 Pa vacuum condition. Sample temperatures 25℃, 70℃, 100℃, 120℃ and 150℃ were selected to reveal the possible influences of sample temperature on atomic oxygen effects. Mass loss of samples was measured by high precision micro-electron balance after the test to obtain the reaction ratio. Emissivity and solar absorbance were measured by TEMP 2000 and LPSR 300. It is shown that the ITO can well protect the base material and the mass loss and the reaction ratio of samples are low. Results also indicate that the sample temperature has little effect on the mass loss, but a great effect on the physical property.
