用Ｘ射线光电子能谱（ＸＰＳ）分析研究了铀金属的不同表层在ＣＯ气氛中２５、８０和２００℃时的表面反应。研究结果表明：ＣＯ与铀金属表层反应后，氧化物中氧含量减少，Ｏ／Ｕ比值随ＣＯ进气量的增加而减少；ＣＯ对铀金属表面的还原效果随温度和铀表层氧化程度的提高而加强；在ＣＯ气氛中，铀表面具有一定的抗氧化性。
The surface reactions of different uranium metal surfaces at 25, 80 and 200 ° C in a CO atmosphere were investigated by X-ray photoelectron spectroscopy (XPS). The results show that the oxygen content decreases and the O / U ratio decreases with the increase of CO input when the reaction of CO with uranium metal surface. The reduction effect of CO on uranium metal surface increases with the increase of temperature and uranium surface oxidation And strengthen; in the CO atmosphere, uranium surface has a certain degree of oxidation resistance.
