堆内水化学环境下低中子注量辐照对锆合金表面氧化膜化学形态的影响分析
Analysis of the influence of low neutron fluence irradiation on chemical morphology of oxide film on zirconium alloy under in-pile water chemistry environment
摘要
Abstract
This study employs X-ray photoelectron spectroscopy and Raman spectroscopy to investigate the chemical morphology and phase structure of the oxide film formed on a Zr-Sn-Nb alloy surface under the coupled effect of low neutron fluence(4.8×1018 cm-2)irradiation and in-reactor water chemistry corrosion.The results show that,in addition to the stable monoclinic ZrO2,suboxides(ZrOx)and hydroxyl groups(-OH)are detected on the oxide film surface at etching depths of 0 μm(surface),0.2 μm,and 0.7 μm,indicating that the irradiation-corrosion coupling effect significantly broadens the spatial distribution range of suboxides.Raman spectroscopy further confirms the irradiation-induced introduction of high concentrations of oxygen vacancies and Zr3+.These findings demonstrate that the coupled effect of low neutron fluence irradiation and water chemistry corrosion significantly modulates the microstructural defect characteristics of the zirconium alloy oxide film,providing important experimental evidence for understanding the evolution mechanism of the oxide film during the initial in-reactor service period of zirconium alloys.关键词
