Which material failure risk increases as hull rivets age?

💡 Explanation

Galvanic corrosion risk occurs because the electrochemical potential difference widens between dissimilar metals as the protective coatings on the rivets degrade, leading to accelerated corrosion of the anodic metal; therefore, accelerated deterioration happens with age, rather than by other possible aging effects.
