Corrosion is the destruction or deterioration of a material because of reaction with its environment [1]. Most common corrosion protection method is the use of paints or organic coatings on active metals such as low carbon steel. Whilst many electrochemical corrosion cells Galvanic Anode - Wikipedia - [PDF Document]Jul 13, 2016In brief, corrosion is a chemical reaction occurring by an electrochemical mechanism.[1] Duringcorrosion there are two reactions, oxidation (equation 1), where electrons leave the metal (and results inthe actual loss of metal) and reduction, where the electrons are used to convert water or oxygen tohydroxides (equations 2 and 3).[2]Galvanic current definition of galvanic current by wje primergalvanic corrosiongalvanic current [ kur´ent ] 1. something that flows. 2. specifically, electricity transmitted through a circuit . alternating current a current that periodically flows in opposite directions; its amplitude fluctuates as a sine wave. convection current a current caused by movement by convection of warmer fluid into an area of cooler fluid. wje primergalvanic corrosion
