Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the ...
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...

Galvanic corrosion, therefore, may be prevented by altering the design of the machinery. Galvanic corrosion is sometimes used to extend the life of materials such as zinc coatings on carbon steel and zinc anodes in water heaters. However if not considered, it can lead to unexpected failures. ...
Galvanic Corrosion vs. Electrode Potential Introduction to electro chemical series and corrosion of metals. The potential difference between an anode and a cathode can be measured by a voltage measuring device but since the absolute potential of an anode or cathode cannot be measured directly - ...
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...
