Passivation (chemistry)

Passivation, in physical chemistry and engineering, refers to a material becoming quot;passive,quot; that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.
