Nope, breeze is speaking of electrolysis. It's one type of corrosion. Oxidation is another and does not require dissimilar metals nor a conductive path. It is the one metal that breaks apart itself to go back to its raw form. Iron starts red and ends red. Copper is a bluish greenish. Aluminum is white. Oxidation will happen to every metal that has been improved. Unless you're talking about the carbon mixed with steel or alloys counting as dissimilar metals (i.e. brass) then your terms only include the electrolysis type.
