摘要:

为了研究空间原子氧(AO)环境和摩擦材料的相互作用机理,以MSTS-1型真空摩擦磨损试验机为平台,研制了可用于模拟空间AO环境下摩擦学试验的AO束流源。该AO源的束流直径超过Æ50mm,通量密度为2.6×1015atoms×cm-2×s-1AO平均能量510eV。常用空间材料Kapton薄膜的AO暴露试验结果也与国外空间飞行试验结果相似。该AO源工作状态稳定、束流纯净、运行气压低、小巧轻便,满足了空间摩擦学试验的特殊要求,并可广泛用于空间AO环境和摩擦材料的相互作用效应模拟研究。

Abstract:

In order to investigate the interaction mechanisms between space atomic oxygen (AO) environment and friction material, an AO beam source for space tribology test was developed on the basis of MSTS-1 vacuum tribometer. The radius of beam area is more than Æ50mm, the flux density and energy of the AO beam are 2.6×1015atoms×cm-2×s-1 and 5~10eV, respectively. The typical spacecraft material, i.e. Kapton, is exposed in the simulation facility, and the test results are similar to those of space flight exposure tests. In addition, the performance of the AO source is very stable and can work in high vacuum, the composition of the beam is pure. So the AO source not only satisfies all the special requirements of space tribology test, but also can be used to other space environment simulation test.
