corrosion
Stray current corrosion is similar to galvanic corrosion
in the way it acts but differs in the way it is caused. In
galvanic corrosion, it is the potential differences on
the metal that initiate corrosion.
As the name implies, stray current corrosion is
caused by stray currents. Stray currents can arise as
a result of faults in the boat’s electrical system, such
as connections and splices that are exposed to mois-
ture or bilge water, equipment that is faulty as a result
of damage or wear, or an electrical system that is in-
correctly connected. Stray current corrosion can also
be caused by stray currents from neighbouring boats
or equipment for connecting to a shore-based power
supply at quays.
