Which outcome results when a metal corrodes due to galvanic corrosion in humid condition?

💡 Explanation

When dissimilar metals are in contact in a humid environment, galvanic corrosion occurs because one metal acts as an anode and corrodes preferentially, weakening because of electrochemical reactions. Therefore a loss of structural integrity results, rather than increased conductivity, thermal resistance or protective layer buildup, as those would negate the degradation.
