The chart can be used to determine the likelihood of a galvanic reaction, and galvanic corrosion or bimetallic corrosion, between two different metals in a seawater environment. The closer a metal or an alloy is in the galvanic series, the less are the effects of galvanic corrosion compared to...
A detailed galvanic corrosion chart ranks various metals plotted against a scale that extends from most-noble or most-cathodic (most resistant to corrosion) metals to least-noble or least-cathodic (least resistant to corrosion).The galvanic scale can also be expressed in voltage potential of these...
In order for galvanic corrosion to occur, three elements are required. Two metals with differentcorrosion potentials Direct metal-to-metal electrical contact A conductive electrolyte solution (e.g. water) must connect the two metals on a regular basis. The electrolyte solution results in a “conduc...
Corrosion Problem when Connecting Copper and Iron/Steel A very common connection in piping systems are copper and iron/steel. with this connection iron/steel corrodesmany times fasterthan iron/steel alone. Unit Converter TemperatureoC K oF
However, there are many factors that can affect the corrosion resistance, including the alloy of the metal, and the environment. The galvanic chart shown below is based on the metals being submerged in seawater and should be used only as a general outline. Galvanic Series Chart How to Prevent...
However, from the same chart, we can see that copper and stainless steel can produce a galvanic cell where the stainless steel is the corroding terminal. This is most likely what is causing the premature corrosion failure.Frank Altmayer

Corrosion 1. Introduction Galvanic corrosion is a stubborn problem in industry. For example, it has been limiting the use of magnesium (Mg) alloy parts in the automobile industry [1] due to the high chemical activity of Mg [2]. This type of corrosion has been very well understood theoretica...
