Tribology dataset: Fe-Cr Composite Coatings Wear Analysis SEM Images and Friction Data

This dataset comprises 500 high-resolution SEM micrographs of Fe-Cr composite coatings after ball-on-disk wear tests, along with matched friction-coefficient time-series CSV files for each class (0–4). It supports automated wear-pattern classification using deep learning and quantifies tribological behavior under controlled conditions (20 N load, 100 RPM, 1000 m sliding distance) .本数据集包含500幅经球-盘磨损试验后的铁铬（Fe-Cr）复合涂层高分辨率扫描电子显微镜（Scanning Electron Microscope, SEM）显微图像，以及对应每个类别（0至4）的匹配摩擦系数时间序列CSV文件。该数据集可用于开展基于深度学习的磨损形貌自动分类任务，并可量化表征受控实验条件（20 N载荷、100 RPM转速、1000 m滑动距离）下的摩擦学行为。
