Morphological estimation of pitting corrosion on vertically positioned 304 stainless steel using acoustic-emission duration parameter

Corrosion Science, 2019
A morphological estimation of the pitting corrosion of type 304 stainless steel using the acoustic emission (AE) duration parameter is proposed in the present work. The pit morphology depending on Cl− concentration and gravity was investigated.

Interaction between pitting corrosion and critical flow velocity for erosion-corrosion of 304 stainless steel under jet slurry impingement

Corrosion Science, 2019
The interaction between pitting corrosion and critical flow velocity (CFV) for erosion-corrosion of 304 stainless steel under slurry impingement was investigated through electrochemical tests, scanning electron microscopy and X-ray photoelectron ...

Metallography of pitting corrosion

Materials Characterization, 1992
Abstract 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

Inhibition of Pitting Corrosion

CORROSION 1989, 1989
Abstract The present state of knowledge in the field of inhibition of pitting is critically assessed and illustrated by selected examples taken from world literature and personal experience. Especial attention is paid to the following two decisive factors: -passivity, which is responsible for pitting (crevice) corrosion when locally ...

Scaling Structure of Pit Profile in Pitting Corrosion

Journal of the Physical Society of Japan, 1991
A 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

Mechanisms of Pitting Corrosion

2011
Pitting 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

Aluminium corrosion studies. IV. Pitting corrosion

Australian Journal of Chemistry, 1978
Measurements are reported for the variation of the open-circuit potential, Er, of aluminium in oxygen-saturated sodium salt solutions. The value of Er was independent of SO42- and NO3- concentrations and similar to the value obtained for water (0.04 (s.h.e.)).

Crevice Corrosion and Pitting

2009
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.
