    Research data for: "Analyzing the 3D morphology of particle systems coated by mechano-fusion using micro-CT image data"
    (Technische Universität Bergakademie Freiberg, 2026-06-17) Seyffer, Judith Miriam; Gräfensteiner, Phillip; Rieder, Philipp
    This dataset contains micro-computed tomography (micro-CT) and high-resolution scanning electron microscopy (SEM) image data of alumina host particles coated with polytetrafluoroethylene (PTFE) guest particles via mechano-fusion, a dry particle coating process. The data supports quantitative analysis of 3D coating morphology using geometric descriptors including coating thickness, surface area coverage, and contact loss. Micro-CT scans of the in epoxy resin embedded particles were acquired with a Zeiss Xradia 510 Versa across two fields of view (upper and lower part) of a 1 mm × 1 mm × 2 mm sample. The dataset includes raw reconstructed image stacks alongside phase-wise, aggregate-wise, and host-only segmentation outputs generated via a hierarchical segmentation pipeline developed as part of the research. SEM images of five polished cross-sections of the same sample were acquired with a Tescan Amber using a backscattered electron detector. An ilastik pixel classification model for SEM image segmentation is also provided. This dataset is associated with the publication "Analyzing the 3D morphology of particle systems coated by mechano-fusion using micro-CT image data."
