Which consequence accelerates corrosion when dissimilar metals join via seawater electrolyte containing sodium chloride?

💡 Explanation

When dissimilar metals are immersed in electrolyte (seawater with NaCl), a galvanic couple forms because difference in reduction potentials causes electron flow oxidizing one metal. Therefore, galvanic corrosion erodes the anode, rather than crevice or pitting corrosion needing structural features or uniform corrosion requiring material homogeneity.
