Isn't that just galvanic corrosion?
- robocat 4y agoGalvanic is two dissimilar metals, usually with an electrolyte like wet soil or water. One metal will corrode far faster than the other e.g. zinc sacrificial anode will corrode to protect iron. Corrosion due to electric currents is different. A few Volts in reverse and you could make iron the anode to corrode and protect a zinc cathode (Cathode and Anode depend on current direction, e.g. they swap when charging a battery). Two parts made of the same metal can be can be corroded with an electrolyte between them, with low AC or DC voltage driving differences.
