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 ...

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 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.

Pitting corrosion is a type of corrosion that attacks a local area of the metal and eventually leads to the formation of holes in the metal. Pitting corrosion can lead to stress corrosion cracking, an example of which collapse of the Silver Bridge in West Virginia, USA happened in 1967.

Jul 19, 2024 · 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 …

Mar 14, 2019 · 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.

Feb 20, 2025 · Pitting corrosion is a highly localized and destructive form of material degradation that affects metals, especially those that rely on a protective passive layer, such as stainless steel.

Oct 26, 2020 · 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 is a localized form of corrosion by which cavities or "holes" are produced in the material. Pitting is considered to be more dangerous than uniform corrosion damage because it is more difficult to detect, predict and design against.

Feb 25, 2025 · Pitting corrosion is a localized process that infests metal surfaces with crater-like pits often filled with white, black, or red powdery corrosion by-products. Corrosion pits can be isolated or grouped in colonies, symmetrical or irregularly shaped, reaching deep into metal or spreading in a horizontal direction.
