Galvanic Corrosion | American Galvanizers Association
There are four elements necessary for corrosion to occur in a galvanic cell: Anode - The electrode where galvanic reaction (s) generate electrons - negative ions are discharged and positive ions are formed. Corrosion occurs at the anode. Cathode - The electrode that receives electrons - positive ions are discharged, negative ions are formed.
