Protection against atomic oxygen erosion of oxide coatings for spacecraft materials

  • 摘要: 采用磁控溅射方法在航天器常用材料聚酰亚胺(Kapton)表面沉积无机氧化物涂层(TiO2和SiO2),来提高材料的抗原子氧剥蚀性能.通过选择试验材料和参数,优化了沉积涂层的工艺,以克服容易产生裂纹的缺点.对材料进行了原子氧效应地面模拟试验,结果表明,在Kapton上沉积涂层后,质量损失下降了2个数量级.另外,有涂层的Kapton表面基本没有变化并且没有出现裂纹.其中,TiO2由于热膨胀系数更接近Kapton,比SiO2的防护效果更好.
