Uniform corrosion originates from chemical attack.

If it was uniform, wouldn't that exclude the possibility of different regions?

yea , thats what i understand but in a cprrosion course the instructor said that there is anodic and cathodic sites but we cant separate them , so by this way he exclude that it is chemical and mean that it is electrochemical ???
