Abstract:

Environmental effects have been largely ignored in the development of corrosion mechanisms and concepts related to the passivity of metals and alloys. In the development of passivity mechanisms, including the formation of passive films, the composition of the electrolyte has been given virtually no consideration except in so far as it provides protons and hydroxyl ions. Yet the breakdown of passivity is often tied to specific ion adsorption and the chloride ion is attributed with unique properties that are evident for this ion in no other area of chemistry. The purpose of this communication is to reexamine the role of environmental effects, specifically anion effects, with the view of establishing a concept that will be a useful and guiding principle describing the influence of anions in corrosion and passivity.
