Galvanic Corrosion Simulator DEMO Version


Galvanic corrosion in salt water, where the more active metal is rapidly corroded when in an electrical contact with a more passive metal.

Galvanic series in sea water shows the activity of different metals and alloys. If the potential difference is greater than 0.2 V, then the metals should not be combined unless additional corrosion prevention techniques are applied or dealing with a very dry application environment.
