Simply speaking, galvanic corrosion is the damage or deterioration of metal that takes place between dissimilar metals because of an electrochemical reaction.

Galvanic reaction is the principle upon which batteries are based. See the table of standard electrode potentials for more details. Galvanic series (most noble at top) The following is the galvanic series for stagnant (that is, low oxygen content) seawater. The order may change in different environments.

Below is a galvanic reaction chart for dissimilar metals. Please understand that green represents "lower risk" not "no risk." It should be noted that if sacrificial plating is incorporated in the fastener design, then galvanic action can result in the deterioration of the sacrificial coating, rather than of the fastener.

Galvanic corrosion describes a process in which two (or more) dissimilar metals are used together, resulting in a corrosive process. A common application that may experience galvanic corrosion is using an attachment, such as a bolt, that is of a different metal than the primary structure, such as a beam. Table of Contents

Essentially, galvanic corrosion occurs when two different metals immersed in an electrolyte are joined together. In this scenario, the base or the metal with lesser nobility will undergo corrosion. Thus, the corrosion rate can be determined based on the nobility of metals and the electrolyte to which they're exposed. Advertisement

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.

Galvanic Chemistry Dictionary & Glossary

Corrosion potential and the galvanic series. When a metal corrodes in an electrolyte, atoms from the metal separate into ions and electrons (e - ), with the ions dissolving into the electrolyte. For example, for iron (Fe) the reaction is: Fe → Fe 2+ + 2e −. This is called an anodic reaction and Fe 2+ ions are formed.


Mixing Metals in Fasteners

The galvanic series determines the electrochemical potential and nobility of metals and metal alloys. Corrosivity Each alloy or metal has a distinctive corrosion potential. The more negative a metal or alloy is, the more likely it is to suffer galvanic corrosion.

The Galvanic Series, also called the electro-potential series, lists metals in the order of their nobility. (Noble metals are those that are resistant to corrosion and oxidation.) When two metals are immersed in an electrolyte, while also being connected externally by a conductor, the less noble metal experiences galvanic corrosion.

Galvanic Series (electrochemical series)

Galvanic/Dissimilar Metal or Bimetallic Corrosion is a type of electrochemical corrosion, where a material corrodes if it comes in contact with another material in the presence of an electrolyte. During product design, engineers should select material ensuring the dissimilar metal corrosion has the minimum or a positive impact on product function.

Galvanic or voltaic cells involve spontaneous electrochemical reactions in which the half-reactions are separated (Figure \(\PageIndex{2}\)) so that current can flow through an external wire. The beaker on the left side of the figure is called a half-cell, and contains a 1 M solution of copper(II) nitrate [Cu(NO 3 ) 2 ] with a piece of copper metal partially submerged in the solution.
