Abstract Alloy 82, used as weld metal in Pressurized Water Reactor (PWR), was exposed to hydrogenated steam at 400 °C and to simulated primary water at 340 °C. A comparative study of the oxide layer formed on the alloy surface in both environments was performed to confirm that steam conditions were representative of accelerated primary water conditions. For this purpose, the oxidation products were investigated at a nanometer scale using Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectrometry (XPS) and Transmission Electron Microscopy (TEM). Results obtained in both conditions are compared and the influences of heat treatment, test duration and surface preparation are studied.

合金 82 在 340 °C 标称 PWR 一次水中和 400 °C 氢化蒸汽中形成的氧化皮表征

摘要 82 合金在压水反应堆 (PWR) 中用作焊缝金属，暴露于 400 °C 的氢化蒸汽和 340 °C 的模拟原水中。对两种环境中合金表面形成的氧化层进行了比较研究，以确认蒸汽条件代表了加速的初级水条件。为此，使用扫描电子显微镜 (SEM)、X 射线光电子能谱 (XPS) 和透射电子显微镜 (TEM) 在纳米尺度上研究氧化产物。比较在两种条件下获得的结果，并研究热处理、试验持续时间和表面处理的影响。
