that' question about corrosion of metals

Corrosion is an oxidation process of metals in the presence of water. For iron this process is known as rusting. The process of oxidation w.r.t aluminium and zinc in corrosion.
The rusting of ordinary iron and steel is the most common form of corrosion.
The effects of corrosion are often (ok, essentially always) undesirable. Rust is generally formed at the surface of the metal, and doesn't adhere to the surface.
When rust flakes off, the underlying metal is exposed to further corrosion (a process called pitting), and eventually the structural integrity of the metal disintegrates.

When exposed to oxygen most metals will oxidize.
Iron forms iron oxide (red, flaky material)
Zinc forms zinc oxide (white, very hard) This protects the underlying zinc from further corrosion.
Similar with Aluminium.

Oxygen still bonds with them, and all corrosion is rapid oxidation. Check what conditions may promote the bonding of oxygen with your metal--heat, moisture, electrical charge, etc. Remember that stability plays a part in the bonds formed.

Corrosion is a more scientific expression for rust. They are the same.
