Master Corrosion Control 2026 – Ace the Basics and Safeguard with Style!

Galvanic corrosion happens when two different metals are electrically connected in the presence of an electrolyte, forming a galvanic couple. The metal that is more active becomes the anode and corrodes, while the more noble metal acts as the cathode. This available electrochemical pathway only exists when dissimilar metals are in contact, so that electron flow and ion movement can drive corrosion at the anodic metal. Moisture or oxygen influence the rate, but without two different metals in contact, galvanic corrosion doesn’t occur.
