铀表面粘污的红外和拉曼光谱分析

IR and Raman Spectra Investigation of Contamination on Uranium Surface After Manufacture

机加工后的铀试件,表面不可避免地残留下影响铀试件腐蚀行为的冷却液粘污。本工作研究利用红外光谱和拉曼光谱对铀试件表面的粘污情况进行表征。实验研究初步结果显示,红外光谱、拉曼光谱能够定性地评估铀试件表面的粘污物和粘污程度,且观察到残余在铀表面的机加工冷却液分布不均匀。

The residual coolant on the surface of uranium after manufacture is inevitable and it will be effective on the corrosion of uranium. IR and Raman spectra were used to investigate the contamination on the uranium surface in this study. The results show that Raman spectrum and infrared spectrum can distinguish the contamination species and determine the amount of contamination. The results also show that the distribution of contamination is not uniform.
