Which metals undergo differential aeration corrosion?

  1. May 5, 2016 #1
    Hi, I am trying to learn about different types of corrosion. I have read that iron can undergo differential aeration corrosion, but not zinc and aluminium. I do not see why...both can be reduced by oxygen and both have a passive film. Can somebody explain why?

    Thanks
