stray current corrosion

Part 2: Understanding Marine Corrosion—Electrolytic Corrosion

Stray current corrosion is similar to galvanic corrosion, except that a current source is added to the circuit. Source: USPS. Electrolytic or stray current corrosion is related to galvanic corrosion, discussed last month. It functions similarly, but with the addition of an external electrical source to the corrosion equation, which significantly accelerates the reaction. It…
