Galvanic corrosion, also known as galvanic action or galvanic cell corrosion, is a type of corrosion that occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte. This process is driven by the difference in electrode potentials between the two metals, which creates an electric current that flows from the more active (anodic) metal to the less active (cathodic) metal. The anodic metal corrodes more rapidly than it would in isolation, while the cathodic metal is protected from corrosion.

The rate of galvanic corrosion depends on several factors, including the type of metals involved, the area ratio of the two metals, the conductivity of the electrolyte, and the environmental conditions. To mitigate galvanic corrosion, various strategies can be employed, such as using sacrificial anodes, applying protective coatings, or isolating the metals with insulating materials. Understanding and managing galvanic corrosion is crucial in various industries, including marine, oil and gas, and infrastructure, to prevent costly damage and ensure the longevity of structures and equipment.
