Fig. 7: Three-dimensional renderings of a growing pit.

From: Revealing the growth kinetics of atmospheric corrosion pitting in aluminum via in situ microtomography

Fig. 7

3D renderings of Pit 4 and the evolving droplet and corrosion product are shown at the indicated time intervals in (a) to (g). Each color change of the pit reveals additional growth of the pit relative to the two previous time intervals. The initial droplet under which this pit nucleated and a nearby droplet are labeled in (a). The arrows in (a–c) correspond to the same locations shown in Fig. 6 at each time step. The scale bar in (a) and the grid size around each rendering is 20 μm.
