Fig. 6: Trends in pit growth rates as a function of environment.
From: Pit growth kinetics in aluminum: effects of salt loading and relative humidity
For the four environments examined in this study, distributions of (a) initial and (b) secondary pit growth rates are provided. Some pits exhibited multiple secondary growth rates – all of these are included in (b). (c) shows a plot of secondary growth rate as a function of initial growth rate; connected points highlight secondary growth rates that were associated with a single pit. Contour lines are provided in (c) as a visual guide to compare initial and secondary growth rates.
