Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte. A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices. This phenomenon is named after Italian physician Luigi Galvani (1737-1798). WebJul 16, 2024 · Titanium does Not Obey the Rules of Galvanic Corrosion. In galvanic corrosion (also known as bimetallic corrosion), if two metals are coupled together (directly or indirectly), one will act as the anode and the other as the cathode when exposed to an electrolyte.
