Description: Galvanic corrosion is a form of localised corrosion, which happens whenever two metals or alloys, with a potential difference of at least 50 mV, are in direct contact with each other and with a corrosive electrolyte. The least noble of the two metals or alloys will become the anode in the corrosion reaction. This animation expalins the mechanism of galvanic corrosion. The least noble of the two metals in this example is aluminium.
Keywords: galvanic corrosion • corrosion potential • corrosive electrolyte
