Passivation improves the surface condition of stainless steel by dissolving iron that has been embedded in the surface during machining and/or forming. If passivation treatments do not occur, the embedded iron may corrode and give the appearance of rust spots on the stainless steel.
How Passivation Works:
First, stainless steel components are treated by being immersed in a nitric or citric acid solution to dissolve the embedded iron. Then, a thin, transparent, oxide layer (or film) forms, resulting in the restoration of the original corrosion-resistant surface.
