摘要
采用电化学方法研究了铀铌合金在 50 μg/ gCl- ,2mol/LH2 SO4和 1mol/LNaOH介质中的电化学腐蚀行为 ,并用X射线光电子能谱 (XPS)分析了电化学腐蚀产物的组成和价态。结果表明 ,铀铌合金的电化学腐蚀行为与溶液的 pH值关系极大 ,铀铌合金电化学腐蚀后表面总是存在合金组分铌的富集。
The electrochemical corrosion behaviors of uranium-niobium alloy in Cl - H 2SO 4 and NaOH solutions have been researched by electrochemical method,and the composition and valence state of the corrosion products have been analyzed by x-ray photoelectron spectroscopy (XPS). The results indicate that the electrochemical corrosion behavior of uranium-niobium alloy is profoundly dependent on the pH value of solutions, and that niobium is always enriched at the uranium-niobium alloy surface after electrochemical corrosion.
