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.

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.

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, …

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, …

Physical chemistry and engineering define passivation as a process that makes materials “passive” and less likely to corrode or react with environmental elements. The process makes certain metals and …

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.
