ELECTROCHEMICAL CORROSION BEHAVIOR OF URANIUM-NIOBIUM ALLOY IN AQUEOUS SOLUTIONS

Fu Xiaoguo, Wang Xiaolin, Bai Chaomao, Zhao Zhengping  
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.
