Differences between 3D, 2D, and 1D corrosion: (a) schematic drawing of a typical bulk bicontinuous dealloying corrosion morphology; (b) schematic drawing of a typical pitting corrosion morphology with the volume set as transparent; the grain boundaries (GBs) were not displayed because both intergranular and intragranular pitting can occur; (c) schematic drawing of a typical intergranular corrosion morphology with the volume set as opaque; the sides of the cube display the cross-sectional views; (d) schematic drawing of 1D wormhole corrosion in a polycrystalline material; the upper half is a cross-sectional view showing discontinuous dots (i.e., voids filled by molten salt) along the GBs; the bottom half is a volumetric cutaway along the GBs where the 1D percolating network of tunnels on the grain surfaces is clearly shown in red; the dark blue color in (a) to (c) indicates free space such as cracks, voids, crevices etc., while the red color in (d) indicates wormholes filled with molten salt; (e) a representative false-colored SEM image showing the cross-section of Ni-20Cr after corrosion; (f) FIB-SEM 3D reconstruction of the volume shown in (e).
