Oxide thickness and hydrogen absorption data in Zircaloy-2 subjected to Pt catalysts in hot pressurized water

The data includes the microstructures of Zircaloy-2 in the as-received condition, after oxidation at 288 deg C, 90 bar for periods of 25, 60 and 150 days. Some tests were performed in hydrogen water chemistry conditions while others were performed in normal water chemistry conditions. The Pt catalysts were added on these surfaces to analyze the corrosion kinetics in these specimens. By using Focused ion beam studies of the cross-sectional cuts, we have developed the corrosion mechanisms and linked the corrosion rate to the hydrogen abosrption in these materials. The data will include: (1) Scanning Electron Microscopy pictures (2) Hydrogen absorption data (3) Oxide-metal interfaces as revealed by SEM (4) FIB cross-sectional cuts as revealed by SEM (5) Pt nanoparticles distributions on oxidized Zircaloy surfaces本数据集包含锆合金-2（Zircaloy-2）在供货态、以及在288℃、90巴工况下分别氧化25天、60天和150天后的微观组织。部分试验采用氢水化学工况开展，其余试验采用常规水化学工况进行。为分析试样的腐蚀动力学特性，研究人员在试样表面负载了铂（Pt）催化剂。通过对截面切片开展聚焦离子束（Focused Ion Beam, FIB）分析，本研究阐明了腐蚀机制，并建立了腐蚀速率与该类材料吸氢行为之间的关联。 本数据集包含以下内容： (1) 扫描电子显微镜（Scanning Electron Microscopy, SEM）图像 (2) 吸氢数据 (3) 扫描电子显微镜观测得到的氧化层-金属界面 (4) 扫描电子显微镜成像的聚焦离子束截面切片 (5) 氧化态锆合金表面的铂纳米颗粒分布情况
