Multi-dimensional mapping. High-resolution 3D models and chemical information of the surface of a WC-Co insert after dry machining a UNS A92024-0 Al alloy. A series of 36 SEM images using a BSE detector and a series of 36 EDXS maps were acquired concurrently at 20 kV from the same viewpoints of the cutting tool. The 3D mesh (Fig. 4) of the insert was reconstructed from the series of BSE images. Finally, the 3D mesh was textured with three series of images obtained by processing semi-quantitatively the EDXS maps. The figure shows the visualization from three viewpoints of the 3D mesh textured with Atomic %, Weight % and phases. The resulting 3D models can be explored interactively from within the section S1 of the Supplementary Material. (a) The model clearly shows the distribution of the secondary adhesion wear. (b) A thin layer of Al covers large areas of the insert. (c) The content ratios of O, Mg and Cu and Al are different at the edge, the flank and the primary and secondary rake face of the tool.
