Reiäkkökorroosio
Reiäkkökorroosio, also known as pitting corrosion, is a localized form of corrosion that creates small holes or pits in a metal surface. This type of corrosion is particularly dangerous because it can severely weaken a material with relatively little loss of total mass, making it difficult to detect in its early stages. It typically occurs in environments that contain aggressive ions, such as chloride ions, which can break down the passive film that usually protects the metal.
The mechanism of pitting corrosion often begins with a small defect or imperfection in the metal's surface,
Common materials susceptible to pitting corrosion include stainless steels, aluminum alloys, and nickel alloys, especially in
The consequences of pitting corrosion can range from aesthetic damage to catastrophic failure of components, particularly
