Aluminum Fuel Tanks. In the case of aluminum tanks, aluminum is a highly conductive metal that relies on an oxide layer for its corrosion protection properties. Low levels of ethanol, such as E10 (10%), are usually not a problem in aluminum tanks because the oxide layer provides a good measure of protection.

Galvanic corrosion often is the cause of failure in aluminuni alloy designs# Aluminum, for sea-v/ater service, gives best results if it is not coupled to other metals* Aluminum can be cathodically protected, but caution.must be employed.

Galvanized bolts, automobile steel and mail boxes, zincs placed outboard engines and steel boat hulls, aluminum blocks on oil rigs, etc. Typical coatings which work on this principle are:-zinc on steel, aluminum on steel, cadmium on steel. It should be remembered that cadmium is only slightly below steel in the galvanic series.

This combines elements of pitting, crevice and galvanic corrosion, and occurs where small particles of foreign matter, in particular carbon steel, are left on a stainless steel surface.

Owners especially concerned about galvanic corrosion can specify an on-board metering system that constantly measures corrosion potential. Checking the meter daily will immediately warn the crew of unusual circumstances underwater. However, most aluminum boats enjoy a corrosion-free life after decades of service, protected only by zinc anodes.

Another important factor for galvanic corrosion is the distance effect. Galvanic corrosion rates are the largest at the interface between the anode and cathode and decrease with distance away from the contact region. As the anodes and cathodes are both good conductors - remember carbon can cause galvanic corrosion by acting as a cathode ...
