摘要
采用X射线光电子能谱 (XPS)和气相色谱 (GC)研究了铀铌合金在 2 5℃与CO反应后表面层的组成和反应气氛的变化 .结果表明 ,铀铌合金与CO反应后 ,表面层形成了UO2 ,UC(或UCxOy) ,Nb2 O5和NbO等多种物相 ,反应气氛中有CO2 生成 .
The surface reaction of uranium-niobium alloy with carbon monoxide has been studied by x-ray photoelectron spectroscopy(XPS) and gas chromatography(GC).The reaction leads to the formation of UO 2,UC/UC x O y ,Nb 2O 5 and NbO on the surface of uranium-niobium alloy after exposure in the atmosphere of carbon monoxide for 72 hours at 25℃.In the meanwhile CO 2 has clearly been detected in the atmosphere after the reactions.The interaction mechanism of uranium-niobium alloy with carbon monoxide has been also discussed.
