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) .
