How Does Passivation Work?

Passivation is a metal finishing treatment that companies utilize to protect and enhance parts against corrosion..

The concentration of the acid removes free iron and other foreign material deposited during part machining. Passivation is simply utilized to remove surface impurities and provide some corrosion resistance. While passivated parts do have a light level of cleansing, they often require additional processes, such as electropolishing, for more intense removal of surface contaminants.
