Fig. 6

Horizontal tomograms showing the evolution of Pit 4 are shown. a Shows top-down views of the evolution of the droplet and corrosion product associated with this pit between 15 h (before pit nucleation) and 71 h. b Shows a top-down view of the corrosion damage associated with this pit. c, d Show horizontal sections along the planes shown in (b). The scale bar in (a, b) is 20 μm and all images are at the same scale. Arrows in (a) at 15 h of exposure highlight the two droplets associated with this pit. The pit nucleated beneath the larger of the two droplets. All other arrows highlight changes in the droplet and corrosion product.
