The crevice corrosion is actually a result of differences in the
concentration of oxygen in the water. The water in the crevice becomes
deficient in oxygen compared to the water on the outside of the crevice.
This sets up an electron flow and as a result there is corrosion.

By definition, electrolysis is always dissimilar metals. Can't comment on
the rest because I deal with the chemistry of water--I'm not a metallurgist.

I thought crevice corrosion in stainless steel occurred because of
electrolysis between the materials (even though they were the same material)
touching each other. I'm not very sure of that though so please don't quote
me on it.
