Passivation

Aetna Plating Co. | Cleveland,OH | Passivation

Passivation is a process that makes stainless steel less susceptible to corrosion as a result of exposure to environmental factors, like air and water. Stainless steel is naturally resistant to corrosion, but when parts are machined, particles like dirt, debris, grease, and machining oils become embedded in the surface, reducing its resistance to corrosion.

Passivation is a combination of cleaning and protective coating. The process begins with cleaning the part to remove all oil, grease, lubricants, forming compounds, and cutting fluids that may have been left behind during the machining and fabrication process. The part is then submerged in a passivation solution, like nitric acid or citric acid base solutions. Passivation removes surface contaminants, and a passive film is formed that improves the stainless steel’s resistance to corrosion.
