WebDec 22, 2024 · The measured pitting potentials ( Figure 3) showed that the spot area had even a slightly higher pitting potential than the non-spot area, suggesting that the appearance of white spots on the surface at least did not deteriorate the pitting performance of a component made of 316 L stainless steel. WebPitting. This is a localized type of corrosion in the form of cavities. These pits come in many forms, including narrow and deep, wide and shallow, and elliptical. In some cases the pitting will undercut and begin to run parallel to the surface. The most common cause of pitting is chloride ions (can be found in salts and bleach) which damage ...

"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 … See more According to Frankel (1998) who performed a review on pitting corrosion, it develops in three successive steps: (1) initiation (or nucleation) by breakdown of the passive film protecting the metal surface from … See more Pitting corrosion is defined by localized attack, ranging from microns to millimeters in diameter, in an otherwise passive surface and only occurs for specific alloy and environmental combinations. Thus, this type of corrosion typically occurs in alloys that are … See more Different types of corrosion inhibitor exist. Among them, oxidizing species such as chromate (CrO 4) and nitrite (NO 3) were the first used to re-establish the state of passivation in the protective oxide layer. In the specific case of steel, the Fe cation being a relatively … See more Sulfur has long been known to contribute to damage. This is true for many materials such as metal corrosion, or concrete degradation. In King Lear, Shakespeare says: See more The pit formation can be essentially regarded as a two step process: nucleation followed by a growth.
