چکیده انگلیسی
To understand the degradation behavior of Zircaloy-4 corroded in LiOH aqueous solution, X-ray diffraction was performed to analyze the crystal structure of Zircaloy-4 oxide formed in three different media. Second ion mass spectrometry (SIMS) was utilized to measure the penetration of Li+ and OHâ into the oxide film when Zircaloy-4 is exposed in LiOH aqueous solution. It was found that the SIMS depth profile of OHâ in the oxide film is in accord with that of Li+, which indicates that there exists OHâ in the oxide film. Based on the results, it is put forward that OHâ diffuses faster than Oâ2 in the oxide films, which can enhance the corrosion rate of Zircaloy-4 and the transformation from tetragonal zirconia (t-ZrO2) to monoclinic zirconia (m-ZrO2). OHâ plays a detrimental role on the oxide film formed on Zircaloy-4.
