Which structural problem frequently developed in early ironclad warship construction due to galvanic corrosion?

💡 Explanation

When iron and copper alloys (commonly used for bolts/fittings) are in contact in seawater, galvanic corrosion occurs because iron acts as the anode, corroding preferentially. Therefore, electrolytic wastage around the rivet joints results, rather than brittle fracture, delamination, or cavitation, which require different chemical or physical conditions.
