Question

iron oxide in case of iron eats up the whole thing while in case of aluminum , aluminum oxide acts as a protective layer?​

Answer 1

Explanation:

Most metals want to corrode back to some form of ore. (Gold is one notable exception.) Corrosion starts with oxidation, where atoms of metal link up with oxygen, followed by a gradual, or not so gradual, breakdown. Rusting is a specialized form of corrosion that only iron and steel go through.

Rust is when the iron oxidizes and flakes off. It’s accelerated by moisture. Flaking exposes fresh metal beneath, which in turn oxidizes and flakes.
