Mechanisms of Crevice Corrosion in Chlorinated Environments

Abstract

Crevice corrosion is considered by many to be the most deleterious form of corrosion because it occurs on shielded areas of a metal surface where visual examination of the underlying metal is difficult, if not possible, and unpredicted catastrophic failures can result. Crevice corrosion has been observed on a variety of passive film forming metals exposed in a number of different environments ranging from high purity water to the human body. This type of corrosion is inherent in metals and alloys that are easily passivated (e.g. stainless steels, aluminum and aluminum alloys, titanium and titanium alloys, and nickel base alloys), but also occurs on iron and mild steel exposed to highly oxidizing or passivating environments. Metal surfaces shielded by gaskets, washers, bolt heads, o-rings, barnacles or other surface deposits are typical sites for this type of corrosion. Keywords: Corrosion; Alloys.
