Fig. 1: In situ monitoring of corrosion processes in the ocean.

From: Electrode array probe designed for visualising and monitoring multiple localised corrosion processes and mechanisms simultaneously occurring on marine structures

a Current maps measured from the electrode array surface after different periods of exposure in the Queenscliff Ocean, Victoria, Australia. b Magnified current maps for the period range of week 11 to week 61. Green arrows in b indicate the locations where the localised corrosion in HAZ was active. Photo of the probe (c1) before and (c2) after 61 W exposure to seawater, and (c3) after cleaning the probe according to ASTM standard G1-03. Calculated corrosion loss: (c4) based on the corrosion current accumulation and (c5) based on the weight loss measurements from surface profilometry.
