What is Passivity? - Definition from Corrosionpedia
WebPassivation is natural process of the buildup of a stable, tenacious layer of metal oxide or protective barrier on the surface of the metal that acts as a barrier separating the metal surface from the environment. Passivity decreases or stops the corrosion process because of the formation of the layer. There are metals, that exhibit a passivity ...
