Time Dependent Development of Aluminium Pitting Corrosion

Figure 6

Data for maximum pit depth of aluminium alloys AA1050, AA3003, and AA5052 exposed in unspecified marine atmospheres for up to 20 years. The trends for maximum pit depth are shown and are bimodal. The changeover to mode 2 occurs at about 2-year exposure. Data from Vargel [4].
