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.

Another way this can happen is if the connection uses two dissimilar metals which results in galvanic corrosion, with the same effect. These problems resulted in a number of house fires in the 1960s and 1970s, and both electricians and the general public became convinced that the aluminum …

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.

Bolts used to join galvanized steel shall be galvanized; plastic coated, stainless steel, or otherwise protected to prevent galvanic corrosion. Bolts used to join aluminum, other than aluminum alloy bolts, must be plastic coated or otherwise protected to prevent galvanic corrosion.

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.

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 ...

The true galvanic corrosion risk, however, needs to be further evaluated through galvanic corrosion current measured between the metals, because the extent of galvanic activity is not always proportional to the difference in the E. CORR of two metals.. For example, the galvanic corrosion of zinc is the highest when coupled to steel than to most other metals such as Ni, Cu or Ti (Mansfeld et al ...
