Replication data for: "Hole annihilation vs. induced convection: Breakdown of different contributions to the photocorrosion mechanism of oxide-covered iron"

The uniform corrosion rate of oxide-covered iron increases under illumination. This dataset contains measurements associated with an investigation of the mechanism of this increase. The samples were polished iron samples. Polished iron was either investigated directly, or anodised to create oxide films with thicknesses of 50-350 nm. The dataset contains the following experimental results: (i) potentiodynamic polarisation curves of polished iron in different electrolytes (acid, neutral, chloride-containing, alkaline) with and without white light illumination; (ii) potentiodynamic polarisation curves of anodised iron with different oxide thicknesses in NaOH with and without white light illumination; (iii) potentiodynamic polarisation curves of anodised iron in NaOH with monochromatic illumination (450-800 nm wavelength); (iv) photocurrent and photovoltage transients of polished and anodised iron in NaOH under different illumination and polarisation conditions; and (v) ex situ UV-VIS spectra of anodised iron with different oxide thickness vs. an aluminium reference. All polarisation curves were measured under controlled convection, which enabled a quantification of different contributions to the overall uniform photocorrosion rate of iron. The dataset contains ASCII files with descriptive filenames and is structured in subfolders indicating the respective methods. A detailed interpretation of the results, and the experimental details associated with the dataset is available in the associated article.

在光照条件下，覆盖氧化物的铁的均匀腐蚀速率增加。本数据集包含了关于这一增加机制的调查研究的相关测量数据。样本为抛光铁样。抛光铁样要么直接进行探究，要么经过阳极氧化以形成厚度为50-350纳米的氧化膜。数据集包含以下实验结果：(i) 在不同电解质（酸性、中性、含氯酸盐、碱性）中，抛光铁在不同光照条件下（有无白光）的动电位极化曲线；(ii) 在NaOH溶液中，不同氧化膜厚度的阳极氧化铁在不同光照条件下（有无白光）的动电位极化曲线；(iii) 在NaOH溶液中，使用单色光（波长450-800纳米）照射的阳极氧化铁的动电位极化曲线；(iv) 抛光和阳极氧化铁在NaOH溶液下，在不同光照和极化条件下的光电流和光电压瞬态；(v) 与铝参考相比，不同氧化膜厚度的阳极氧化铁的现场紫外-可见光谱。所有极化曲线均在可控对流条件下测量，这有助于量化对铁整体均匀光腐蚀速率的不同贡献。数据集包含具有描述性文件名的ASCII文件，并按相应方法组织在子文件夹中。相关文章中提供了对结果和与数据集相关的实验细节的详细解释。
