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
