The underwater metals of the boats, of course, can vary between such things as brass, bronze, stainless steel — and aluminium, as in outboard motors, aluminium boats and stern drives. All of these metals can develop different electrical potentials galvanic ally in the same manner as a battery does.

The corrosion of one of two dissimilar metals is referred to as galvanic corrosion, or dissimilar metal corrosion, and uses the property of electrolysis to diminish the weaker of the two metals. The weaker metal, or anode, has a lower number on the galvanic table in relation to the second metal, the cathode.
Galvanic corrosion (in vessels at sea)
Anodes will protect against the formation of both forms of galvanic corrosion. An example of relative galvanic positions of metals is shown below: Galvanic series for common metals in sea water (relative to silver ) (volts) Magnesium -1.65 Zinc -1.10 Aluminium -0.75 Mild Steel -0.70 Lead -0.55 Copper, brass and bronze -0.25 Stainless steel ...

Galvanized coated steel or stainless steel rods will be typically used where low soil resistivities are encountered and galvanic corrosion may occur between adjacent underground metallic masses and the copper-clad rods. Stainless steel rods have a longer life than the zinc coated steel, but use must be justified based on the higher cost.

Thus a stainless steel screen connected to a mild steel casing would cause far less corrosion on the mild steel than would a bronze or Monel screen. Table I shows the galvanic series. This is similar to the electrochemical series shown in Table II, except that the latter is based on thermodynamically reversible reactions, which are not ...
