väkirymäkorroosio
Väkirymäkorroosio, also known as crevice corrosion, is a localized form of corrosion that occurs in narrow gaps or crevices where stagnant solution can accumulate. This environment is often found in areas where components are joined, such as under gaskets, bolt heads, or in overlapping metal plates. The unique conditions within the crevice lead to a difference in the electrochemical potential between the metal inside the crevice and the metal exposed to the bulk environment.
The process typically begins with the hydrolysis of metal ions that form in the crevice. This releases
Väkirymäkorroosio can be particularly damaging because it is often hidden from view and can lead to rapid
