Localized corrosion:

Localized corrosion is described as the associative removal of metal through corrosion at small zones or areas on a metal surface in contact along with a corrosive environment, commonly a liquid. It commonly takes place while small local sites are attacked at a much higher rate than the rest of the original surface. Localized corrosion takes place while corrosion works alongwith other destructive processes such as stress, erosion, fatigue, and other forms of chemical attack. Localized corrosion mechanisms could cause more damage than any one of those destructive procedure individually. There are many different categories of localized corrosion. Pitting, chloride stress corrosion, stress corrosion cracking, heat exchanger tube denting, caustic stress corrosion, primary side stress corrosion, wastage, and intergranular attack corrosion are elaborate in detail in the Chemistry Fundamentals Handbook.
