Data underlying the study "Local re-immersion behaviour of Ce-based inhibiting layers on AA2024-T3 intermetallics: Enhanced stability through partial dealloying and prolonged exposure"

This data covers the work "Local re-immersion behaviour of Ce-based inhibiting layers on AA2024-T3 intermetallics: Enhanced stability through partial dealloying and prolonged exposure"<br>This work examines how corrosion inhibition at the intermetallic particle level evolves after an initial immersion in a Ce(III)-containing environment, followed by re-immersion in a Ce(III)-free environment. The immersion environment consists of 0.05 M NaCl combined with 0.001 M Ce(NO3)3. Depending on the immersion condition, the duration of exposure ranges from 3 to 72 hours and the inhibitor can be supplied either at the start of immersion (0 s) or at a delay of 30 s. The re-immersion environment consists of only 0.05 M NaCl. Additional details of the experimental conditions are available in the readme file. The immersion and re-immersion behaviour were experimentally monitored through in situ reflected light microscopy. This dataset comprises the pre-processed microscopy images obtained during immersion and re-immersion. Supplementary SEM images aligned with the microscopy images are also provided for the tests with 3 hour immersion duration and no inhibitor supply delay.

本数据集对应研究论文《AA2024-T3合金金属间化合物表面铈基缓蚀层的局部再浸泡行为：通过部分脱合金与延长暴露提升稳定性》
本研究针对金属间粒子尺度的缓蚀效应演化过程展开分析，实验流程为先将试样置于含三价铈（Ce(III)）的环境中浸泡，随后转移至不含三价铈的环境中进行再浸泡。
浸泡环境为0.05 mol/L氯化钠与0.001 mol/L硝酸铈（Ce(NO3)3）的混合溶液。
根据浸泡工况的不同，暴露时长介于3至72小时之间，缓蚀剂可选择在浸泡初始时刻（0秒）添加，或延迟30秒后添加。
再浸泡环境仅包含0.05 mol/L氯化钠溶液。
实验条件的更多细节可参见自述文件（readme）。
本研究通过原位反射光显微镜对浸泡与再浸泡过程中的行为进行实验监测。
本数据集包含浸泡及再浸泡过程中采集并经预处理的显微镜图像。
针对浸泡时长为3小时且未延迟添加缓蚀剂的测试，本数据集还提供了与显微镜图像匹配的补充扫描电镜（SEM）图像。
