Pitting corrosion is in itself a corrosion mechanism, but is also a form of corrosion often associated with other types of corrosion mechanisms. It is characterized by a highly localized loss of metal. In the extreme case, it can appear as a deep, tiny hole in an otherwise unaffected surface. Pitting Corrosion - Structural Integrity Materials ServicesMechanism Typical Locations Features Root Causes Corrective Actions Si Services Pitting is a localized corrosion attack involving dissolution of the tube metal surface in a small and well-defined area. Pitting corrosion can occur in any component in contact with water under stagnant oxygenated conditions.

Pitting is considered to be more dangerous than uniform corrosion damage because it is more difficult to detect, predict and design against. Corrosion products often cover the pits. Pitting Corrosion - an overview ScienceDirect TopicsM.G. Alvarez, J.R. Galvele, in Shreir's Corrosion, 2010 2.04.11.2 Critical Pitting Temperature (CPT). Pitting corrosion of stainless steel and nickel base alloys is characterized by the existence of a CPT, which is defined as the lowest temperature at which the growth of stable pits is possible. At temperatures lower than CPT no stable pitting can occur and only transpassive corrosion takes place.

Pitting occurs when there is a localized breakdown of the stainless steels protective passive layer on an openly exposed surface. Once initiated the growth rate of the pit can be relatively rapid resulting in deep cavities and even through-wall attack. Other metals, such as aluminum, can also exhibit pitting corrosion. Pitting corrosion - TEC EurolabWhen pits are accompanied by slight or moderate general corrosion, the corrosion products often mask them.
