dissimilar materials--materials that might have conflicting coefficients of thermal expansion and the potential for
galvanic corrosion.
If the fluid is nonconductive,
galvanic corrosion does not occur.
An important key property of cadmium coatings is that they provide protection from
galvanic corrosion when in contact with aluminium and this can be achieved with zinc-nickel coatings.
It is likely that the hardware would have suffered significant
galvanic corrosion due to the presence of landfill leachates and gasses.
Furthermore, all the gutters and downpipes are changed to copper due to
galvanic corrosion.
The common corrosion types are mainly
galvanic corrosion, pitting corrosion, filiform corrosion and stress corrosion of these.
Computational models simulate the physics of
galvanic corrosion and the features of a CP system.
In general, metal enclosures provide the best performance but suffer from issues with
galvanic corrosion and oxidation that can reduce their effectiveness.
The Ag3Sn contained in SAC solder joints seems to accelerate tin corrosion because of the
galvanic corrosion mechanism.
