The dataset contains the images recorded during immersion and re-immersion in the different immersion conditions.

The folder names indicate the immersion conditions.

UD03 - no delay in inhibitor supply, 3 hours of immersion
UD24 - no delay in inhibitor supply, 24 hours of immersion
UD72 - no delay in inhibitor supply, 72 hours of immersion
DS03 - 30 sec delay in inhibitor supply, 3 hours of immersion

UD03 data also contains pre-immersion SEM images used for identifying the location of intermetallic particles present on the surface.
