In wet corrosion
the electrochemical process is the dominant factor in contrast to the thick oxide layer in air or other oxidizing environment, at higher temperature with rapid transport processes by solid state diffusion through a growing oxide layer.
To wet corrosion
, the rear section of the automotive exhaust system is mainly exposed.
A trace of corrosion inhibitor was added to prevent wet corrosion
of the inner surfaces of the samples.
I was shown some astonishing two-year-old examples of the very swish Beta model with the front ends oozing wet corrosion
. It was almost as if the car was weeping for the dry and dusty atmosphere of its homeland where it soldiered on for years.
