Galvanic corrosion can be defined simply as being the effect resulting from contact between two different metals or alloys in a conducting corrosive environment. Another term employed is galvanic coupling. When a metal is immersed in any electrolytic solution, it is possible to measure its dissolution natural corrosion. For each solution, it is possible to establish a "galvanic series", that is, a ranking of different metals and alloys as a function of this measured potential. When two different metals or alloys immersed in the same solution are joined together electrically, an electric current will be set up between them, resulting from the short circuit created.

This guide covers the development of a galvanic series and its subsequent use as a method of predicting the effect that one metal can have upon another metal can when they are in electrical contact while immersed in an electrolyte.

Galvanic Corrosion Testing

This website uses cookies to improve user experience. By using our website you consent to all cookies in accordance with our Cookie Policy. Element provides galvanic corrosion tests in accordance with ASTM G71 and client-specific standards for evaluating the behavior of metals and metallic coatings in accelerated corrosion environments. We help you select appropriate materials at the design stage and offer in-field support to give fast answers in live applications. Galvanic corrosion occurs when two or more dissimilar metals electrodes are brought into electrical contact in the presence of a common corrosive electrolyte e. When a galvanic couple forms, the less resistant material becomes the anode and the more resistant the cathode. The cathodic material corrodes slower than normal or not at all, while the corrosion of the anodic material is greatly enhanced.

Historical Version s - view previous versions of standard. More G This type of accelerated corrosion is referred to as galvanic corrosion. Because galvanic corrosion can occur at a high rate, it is important that a means be available to alert the user of products or equipment that involve the use of dissimilar metal combinations in an electrolyte of the possible effects of galvanic corrosion. The metal that will suffer increased corrosion in a galvanic couple in that environment can then be predicted from the relative position of the two metals in the series. The potentials themselves versus an appropriate reference half-cell are listed so that the potential difference between metals in the series can be determined.
