Pitting corrosion - Wikipedia
Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the random creation of small holes in metal. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic (oxidation reaction) while an unknown but potentially vast area becomes cathodic (reduction reaction), leading to ...
Different Types of Corrosion: Pitting Corrosion - Causes and …
What is pitting corrosion? Pitting Corrosion is the localized corrosion of a metal surface confined to a point or small area, that takes the form of cavities. Pitting corrosion is one of the most damaging forms of corrosion.
Pitting Corrosion - an overview | ScienceDirect Topics
Pitting corrosion is a localized attack on the material, which produces cavities or holes. Insight on pitting corrosion is found in the deterioration of the metal surface section. The pit is created by the detachment of the iron ion particle from the metal surface.
Understanding Pitting Corrosion to Prevent Catastrophic Failures
2019年3月14日 · Pitting corrosion, also known as pitting, is a highly localized and aggressive form of corrosion that occurs on metal surfaces. Small areas of the metal corrode preferentially, forming pits, while the rest of the surface remains virtually free from attack.
Pitting Corrosion
2024年7月19日 · What Does Pitting Corrosion Mean? Pitting is a type of corrosion that occurs in materials that have protective films. It is an attack with localized holes on the metal's surface. The attack can penetrate the metal very rapidly, while some parts of the metal surface remain free from corrosion.
How to Effectively Recognize, Prevent and Treat Pitting Corrosion
2020年10月26日 · Pitting corrosion can be prevented or minimized by choosing materials with high pitting resistance that match the service environment. Keeping service temperatures below the critical pitting temperature of the chosen material is also an important factor.
Pitting Corrosion: Causes, Effects, and Preventative Measures
2023年10月6日 · Pitting corrosion is a type of localized corrosion that affects various metals, causing small, deep pits to form on their surfaces. This type of corrosion is insidious, as it progresses at a much faster rate than general corrosion, often leading to severe damage and even component failure.

2022年10月26日 · Pitting corrosion occurs on the surface of many metal materials, including stainless steel and aluminum alloy that enhance corrosion resistance by passivation. Environmental media can cause pitting corrosion of metal materials, especially solutions containing chloride ion.
Why stainless steel corrodes - Nature
2002年2月14日 · Stainless steel typically shows pitting corrosion in a neutral aqueous solution containing as little as 1 mM chloride, wherein the passive current density of dissolution of the steel is...
