What is Galvanic Corrosion and How to Prevent it? -

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). WebThe threaded fastener which is typically small should be lower on the galvanic chart than the parent material being fastened. In some applications, galvanic action can be used advantageously by coupling the part requiring protection to a more positive (less noble) metal which will sacrificially corrode, e.g. "zincs" on boat motors. home plans with closed kitchen
