【摘要】 采用增重法和电化学方法分别研究了金属铀表面经CO处理后在40℃干燥空气中的抗氧化能力和在14mmol/L Cl-溶液中的抗化学介质腐蚀的能力。研究结果表明:金属铀表面经CO处理后,在40℃干燥空气中的抗氧化能力增强;在14 mmol/L Cl-溶液中的抗化学介质腐蚀的能力也增强,而且在实验所用CO剂量范围内,金属铀的抗腐蚀能力随CO剂量的增加而增强。更多还原

【Abstract】 The metallic uranium surface was treated with CO, and then its oxidation resistance in dry air at 40℃ and its electrochemical corrosion resistance in 14 mmol/L Cl- solution were studied by the weight gain method and the electrochemical measurement, respectively. The investigation indicates that both oxidation resistance in dry air at 40℃ and electrochemical corrosion resistance in the above solution are improved after the uranium surface is treated with CO. In addition, corrosion resistance of the treated uranium increases with raising of the CO dose in a certain range.更多还原
