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.

Passivation is a common chemical finishing process using nitric acid or citric acid to prevent corrosion in stainless steel and other metals.

Jun 16, 2025 · Passivation is a chemical surface treatment for stainless steel and other alloys that need corrosion resistance. Passivation removes free iron from the metal surface with nitric or citric acid, …

What Is Passivation? 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.

Oct 18, 2023 · Passivation is a corrosion protection method that relies on the formation of a passive oxide layer on a metal's surface. This layer acts as a barrier, preventing further corrosion.

Apr 4, 2025 · Passivation is a process that makes metals resistant to corrosion by creating a thin, protective oxide layer on their surfaces. This layer prevents the metal from reacting with …

May 5, 2025 · At its core, passivation is a chemical treatment for metal surfaces, particularly stainless steel, that boosts corrosion resistance by forming a protective oxide layer.

This comprehensive guide explores passivation—the critical process that enhances metal corrosion resistance through controlled oxidation. We’ll examine the science behind passive layer formation, …

Jul 15, 2025 · Passivation does not change the dimensions of parts nor add visible coating layers, yet it plays a critical role in long-term performance. This article introduces the definition, principle, industry …
