Electrochemical impedance spectroscopy (EIS) results and analyses demonstrated that the increasing galvanic corrosion rate observed between the coupled dissimilar metals as exposure time prolonged was suppressed by the oxide film effect. The suppression occurred as a result of the transformation of unstable...
10.2.1 Galvanic corrosion involving two dissimilar metals When two dissimilar metals are immersed in an electrolyte they usually develop different potentials in accordance with the theory already presented. If the metals are in contact the potential difference provides the driving force for corrosion. Se...
The surface areas of dissimilar metals in contact are also significant in identifying which metal is more prone to accelerated corrosion. It is not a good idea to have a large cathodic surface that is in contact with a small anodic area. In order to prevent galvanic corrosion, these measures ...
Not all metals play well together. And this spills over in to the world of electronics and the materials used therein. A relatively new and relevant example came about with the advent of RoHS and the desire to identify a "drop-in" replacement for SnPb(Ag
Consider the final use when choosing the welding method for dissimilar materials. For example, welded joints that come in contact with electrolyte fluids need a filler material with a higher corrosion resistance than the metals to slow down the rate of galvanic corrosion. ...

Not surprisingly, known as an often sacrificial anode in preventing galvanic corrosion due to being more active than most metals28, zinc was the most successful in terms of voltage accumulation and reproductively of experiments among the tested metals. Hence zinc was the main focus in the further...

Furthermore, understanding the corrosion behaviour of dissimilar welds is crucial, particularly given that the joining of two metals can heighten susceptibility to galvanic corrosion (GC) due to micro-segregation and formation of IMCs during dissimilar metal fusion welding, along with the creation of ...
