Passivation is the process of treating or coating a metal in order to reduce the chemical reactivity of its surface. In stainless steel, passivation means removing the free iron from the surface of the metal using an acid solution to prevent rust. When the surface iron is removed, the other components of the alloy (primarily chromium, often nickel as well) are left behind as a surface layer over the underlying steel.
At the primary passivation potential, the surface starts to passivate and the current is reversed. The current at this potential (primary passivation potential or E pp) is denoted as the critical anode current density (I crit). I crit is the current density for film formation to supply the metallic ions to be incorporated into the film. 1 Oct 2003 Incorrectly performed, passivation can actually induce corrosion. stainless grades also may be evaluated by means of a humidity test. 24 Feb 2016 Definition - What does Passivate mean?
