Corrosionpedia type of oxide film is formed on the surface of sn in presence of dry chlorine​.

• When iron rusts, oxygen and water react to generate hydrated iron (III) oxide, which forms the oxide coating on the surface of the iron. Layer of unstable oxide: On the surface of noble metals like Ag, Au, and Pt, this is generated. It disintegrates back into the metal and oxygen because the metallic form is more stable than oxide.
• The metal is shielded from corrosion by the oxide film produced by anodic oxidation in oxalic acid. The Eloxal process is the name of the technological procedure. These oxide films typically have a hexagonally arranged porous structure.
• An electrolytic process called anodizing creates thick oxide coatings, typically on alloys of aluminium.
• In the presence of aqueous or ambient air, the surface of many metals spontaneously develops oxide layers.
• If the oxide film serves as a barrier against corrosion, shielding the metal from quick deterioration, it is referred to as a "passive film." Al2O3 is the oxide that forms a self-protective coating on aluminium. The coating stops the metal from oxidising further.
