Which outcome occurs when an epoxy adhesive is used to bond dissimilar metals in humid environments?

💡 Explanation

When dissimilar metals are bonded with epoxy in humid environments, galvanic corrosion occurs because moisture acts as electrolyte, creating an electrochemical cell and accelerating corrosion of the more active metal. Therefore galvanic corrosion at the interface results, rather than alternatives such as plasticization, creep, or stress corrosion, which involve different failure mechanisms and material dependencies.
