What Does Wet Corrosion Mean?

Wet corrosion refers to the degradation and/or rust formation on a metal surface that occurs due to the generation of a reactive electrochemical cell. Wet corrosion can damage metal structures and equipment, including stainless steel.


Corrosionpedia Explains Wet Corrosion

Wet corrosion forms when two different metals are in contact with each other while situated in a fluid environment with salt concentrations. This environment creates an electric potential between the two metals, with the more reactive metal undergoing oxidation and the loss of electrons. Seawater, chloride solutions and acids are some typical electrolytic environments in which wet corrosion occurs. It can be prevented by eliminating the moisture.
