Passivation (chemistry) - Wikipedia
In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment.
What is Passivation? How Does Stainless Steel Passivation Work?
Passivation 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.
What is Passivation? Enhancing Material Durability and ... - Wevolver
2024年5月8日 · Passivation is the process whereby a metal surface is treated to render it less reactive by promoting the formation of an inert oxide coating. This naturally occurring or chemically induced oxide layer shield, protects the material from further corrosion, effectively "passivating" the metal against environmental elements.

What Is Passivation? - HLC Metal Parts Ltd
2024年5月18日 · Passivation is a corrosion prevention process applied to metals like stainless steel, aluminum, and titanium, where a protective layer is formed on the surface through cleaning and chemical treatment, inhibiting further corrosion and enhancing longevity.
What is Passivation and How Does It Work - LEADRP
2024年2月19日 · Passivation is a vital process in many industries to protect metals against corrosion. This extensive corrosion protection method involves forming a protective oxide layer on the surface of the metal to shield it from damaging chemical reactions. In essence, passivation renders the metal passive or inert.
Passivation Explained - Definition, Process & More | Fractory
2023年9月26日 · Passivation is a post-fabrication process that makes a material passive or inert to chemical reactions that can change its composition and ultimately lead to failure. In the industry, the passivation process is typically carried out to make a metal surface more resistant to corrosion or oxidation by building a protective film over it.
Passivated Stainless Steel: All You Need to Know
2024年10月15日 · Stainless steel passivation is a chemical treatment that improves resistance to corrosion by eliminating surface iron, in accordance with ASTM A967 and AMS 2700 guidelines. Unlike the natural oxide layer, passivation quickly forms a protective chromium oxide film.
Passivation of Stainless Steel Parts - Titan Fittings
2024年2月29日 · Passivation is a process that aims to enhance the corrosion resistance of stainless steel parts by removing free iron particles and forming a passive layer on their surface. These free iron particles can react with environmental factors, leading to corrosion, oxidation and discoloration of the metal.
