contactPassivation, generally associated with stainless steel, is a treatment method to protect the metal from corroding through—making the material “passive” to the surrounding environment. Passivation, perhaps counterintuitively, encourages corrosion to occur on the surface, creating a thin layer of a new, non-reactive chemical.
