Oxide Films

Oxide films are thin layers of oxide material that naturally form on the surface of metals when they are exposed to oxygen. These films act as a protective barrier, preventing further oxidation and corrosion of the underlying metal. For example, when iron reacts with oxygen, it forms a rust-colored iron oxide layer that slows down further corrosion. Oxide films are essential in many industries for maintaining the integrity and durability of metal components, as they can influence properties like corrosion resistance, electrical conductivity, and surface appearance.
