What is an Oxide Film? - Definition from Corrosionpedia

An oxide film is normally a thin layer deposited on the surface of a metal which has undergone an oxidation reaction from air or moisture surrounding the material. These oxide films are naturally produced in highly reactive materials from the top of the galvanic series. However, these oxide films can be chemically produced by exposing the surface of the material to controlled oxygen and temperature
