Passivation is a special process used to prevent corrosion by removing the free iron from the base metal surface, creating a thin layer of oxide, covering the surface of the part to protect the base material from corrosion and extending the life of the part. This process is also referred as micro-coating. Passivation is performed by cleaning the parts, removing any contaminants from the surface and then immersion of the part into an acid bath. When the parts are exposed to oxygen after the immersion process, the passive protective layer is formed.
