The initiation of pitting corrosion at MnS inclusions
Corrosion Science, 1993Abstract The dissolution of MnS inclusions in stainless steel exposed in 0.5 M NaCl + 0.5 M H 2 SO 4 + 0.08% H 2 O 2 at the free corrosion potential for 10 s has been studied using simultaneous Auger/EDX analysis and imaging and electron microscopy. Inclusions at different stages of dissolution have been examined.

Metallography of pitting corrosion
Materials Characterization, 1992Abstract Following a brief description of the history of studies of pitting corrosion, a classification scheme is proposed that considers the typical constraints that can be imposed on localized dissolution phenomena. Recent light and electron metallographic studies on a range of austenitic stainless steels have permitted an appreciation for the role

Passive films, which were studied in the previous chapter, are remarkable in their ability to provide corrosion protection to a wide variety of metals and alloys. However, passive films are not perfect and often suffer localized breakdown at certain specific areas.

Mechanisms of Pitting Corrosion
2011Pitting corrosion occurs at passivated metal surfaces during the access of so-called aggressive anions. Halides very effectively attack passivating thin oxide layers, leading to an intense localized dissolution of the metal surface, which is otherwise protected by the passive layer against general dissolution. Chlorides cause the most serious problems

Scaling Structure of Pit Profile in Pitting Corrosion
Journal of the Physical Society of Japan, 1991A growth model is presented to simulate pit formation in pitting corrosion in three dimensions. The pit growth model is described in terms of the anti-diffusion-limited aggregation (anti-DLA) model. Computer simulation is performed to study the scaling structure of a single pit in pitting corrosion. It is found that the bird's-eye view of the corrosion

Abstract Pitting is the most common corrosion attack on aluminum alloy products. This chapter explains why pitting occurs and how it appears in different types of aluminum. It discusses pitting rates, pitting potentials, and pitting resistance as well as testing and prevention methods.

Pitting is one of the most common yet insidious forms of corrosion attack. It is highly unpredictable and difficult to model. The role of films in pitting corrosion is presented in three parts: pit initiation, pit propagation, and repassivation.

The pitting corrosion of nickel has been investigated using potentio-static techniques, optical and scanning electron microscopy. The effect of grain size, cold work, annealing procedure and chlorine ion concentration has been investigated and analyzed from the point of view of the pitting susceptibility and passivity of nickel.
