WebPassivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer, or passivation film, that is less likely to chemically react with air and cause corrosion. WebA non-electrolytic process typically using nitric or citric acid, passivation removes free iron from the stainless steel surface and forms an inert, protective oxide layer. Since there is …
WebOct 31, 2024 · Citric acid passivation refers to the process of using citric acid to prevent corrosion in stainless steel (SS) and other alloys. Through the process of removing free iron ions and forming a protective layer of passive oxide on the surface, stainless steel or any other type of metal can become extremely rust resistant.
