Choose one (1) specific type of corrosion and explain its nature, including how and under what conditions it occurs
Answer (1)
Galvanic Corrosion occurs when two different metals are in electrical contact with each other and are exposed to an electrolyte (like water containing salts). One metal becomes the anode and corrodes faster, while the other acts as the cathode and corrodes slower or not at all. This happens because of the difference in their electrode potentials.Conditions of Galvanic CorrosionTwo dissimilar metalsElectrical contact between themPresence of an electrolyte (moisture or water with ions)Nature The metal with the lower electrode potential (anode) corrodes, while the other metal (cathode) is protected. This type of corrosion is common in marine environments, pipelines, and metal joints.
