What is another term for galvanic corrosion?

Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, leading to one metal corroding faster than it would alone. This term emphasizes the role of dissimilar metals in promoting corrosion through electrochemical reactions. The process is a direct result of the electrochemical potential difference between the two metals, which drives the corrosion of the more anodic metal (the one that is least resistant to corrosion).

Other terms, though related, do not specifically capture the essence of galvanic corrosion. Uniform surface corrosion refers to a general, even wear of metal surfaces, while galvanic cell corrosion is less commonly used and does not emphasize the specific condition of dissimilar metals involved. Electrolytic corrosion describes a broader category of corrosion affected by an electrical current but misses the critical aspect of metal dissimilarity that defines galvanic corrosion. Thus, the correct answer highlights the crucial factor that leads to this specific type of corrosion.
