A metal's position in the series is a key factor in galvanic corrosion effects, where different metals are in contact with one another. Environmental factors, such as oxygen and an electrolyte (usually water) also play a significant role in the speed of the corrosion process

The corrosion rate can be accelerated under a number of conditions if other contaminating metals are present such as copper which may be picked up from brass fittings or as a low level contaminant in the aluminum alloy. Chloride, which is a chemical found in salt water, will also accelerate corrosion.

If the copper cathode is replaced with stainless steel, for example, the initial current is about the same, but after a few hours the galvanic current from the stainless is only a small fraction of that from copper. Thus a stainless steel screen connected to a mild steel casing would cause far less corrosion on the mild steel than would a ...

Galvanic corrosion in re-circulating hot water systems with combined copper and galvanized steel piping corrosion can be very pronounced and some dissolution of the copper piping may and will occur. This is clearly evident at Five Points from the June 10 sample results where the copper levels in each building were dramatically higher in the hot ...

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 ...

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.

Where as copper which is having higher electrode potential acts as cathode gets unaffected. The rate of galvanic corrosion depends upon potential difference between anodic and cathodic metals, ratio of anodic and cathodic area and environmental factors and tendency of the metal to undergo passivity etc.
