Fundamental Investigation of Pitting Corrosion in Structural Metals

Abstract

This report gives a summary of the main electrochemcial features of pitting corrosion of iron, aluminum, magnesium, titanium, and stainless steel in halide solutions. Ohmic and mass transport limited corrosion regions and effect of hydrodynamic flow are described. Barrier films of metal halide salt are formed on the metal surface for these metals in the mass transport limited region. The electrical properties of these salt films were determined. A mechanism is proposed for the protection from pitting of stainless steels by flowing seawater. (Author)
