Galvanic Series (electrochemical series)
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

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

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 Chemistry Dictionary & Glossary
A galvanic (voltaic) cell converts the energy released by a spontaneous chemical reaction to electrical energy. An electrolytic cell consumes electrical energy from an external source to drive a nonspontaneous chemical reaction. Example 2.1.1 2.1. 1. A chemist has constructed a galvanic cell consisting of two beakers.

Mixing Metals in Fasteners
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 series relationships are useful as a guide for selecting metals to be joined, will help the selection of metals having minimal tendency to interact galvanically, or will indicate the need or degree of protection to be applied to lessen the expected potential interactions.
Galvanic Corrosion SSINA
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.

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.

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 Corrosion Common Questions Answered
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.
