红外光谱仪模拟空间原位分析表征系统的研制
|
摘要
对现有傅里叶红外光谱仪进行拓展开发,空间模拟试验系统通过法兰与外置原位真空池及光谱仪相连接,实现样品推送机构的建立.分析单元与主真空室之间采用双闸板阀联用实现双向密封,可独立对材料表面进行快速原位分析.摩擦试样可通过样品精密传送和定位装置移动至分析单元进行表征,实现了模拟空间环境下摩擦表面的原位分析功能,将润滑材料的空间摩擦学行为与其表面及化学状态准确关联,避免环境对摩擦表面的污染,为设计新型空间润滑材料提供可靠的试验依据.
To develop the available fourier infrared spectrometer,the spatial simulation test system was connected with the spectrometer through flange and external in-situ vacuum cell,thus the sample pushing mechanism was established. A double gate valve was used between the analytical unit and the main vacuum chamber,so the two-way sealing can be realized by the combination,and the surface of material can be analyzed in-situ independently. The friction samples can be characterized by the precise sample transmission and positioning device moving to the analysis unit,the in-situ analytical function of the friction surface under simulated spatial environment,the accurately correlation of the space tribological behavior of lubricating material with its surface and chemical state can be realized,and the environmental pollution to friction surface can be avoided. A reliable experimental basis for the design of new spatial lubricating material is provided.
