Which outcome occurred in 18th-century wooden ships when dissimilar metals contacted in seawater?

💡 Explanation

When dissimilar metals contacted in seawater, galvanic corrosion occurred because the electrochemical potential difference creates electron flow, preferentially corroding the more active metal like iron. Therefore, iron fastenings corroded faster, rather than planking rot, growth, or rigging issues which involve different mechanisms and material properties.
