Yes I do, do you? Anodes erode, not corrode.
Erode is to carry away, corrode is to destroy by chemical action.
The metal in an anode is carried away by electricity generated by chemical action. Much like electroplating, a very similar chemical reaction.
Corrosion changes the chemical structure of a substance, erosion simply removes a substance slowly, one molecule at a time.
Corroded aluminum still exists but in an altered state, IE; aluminum oxide.
Which adheres to the parent metal.
Eroded zinc from an anode still exists as zinc, but as particles of zinc in solution, not part of or attached to the parent metal.
At least that is what my text books said. Being that I am not a chemist nore an engineer, I can only take the text as truth since I have no other source of information.
If you have texts that say otherwise I would appreciate knowing what texts those are so I can correct the lessons I was taught.
