WebJan 1, 2024 · The reason for this matter is the galvanic corrosion. Due to high corrosion potential of pure Ag or Fe–Au solid solution, they will act as cathodes of the galvanic cells and iron will act as the anode of the cells. Hence, many galvanic cells will form in the sample. As a result, iron will corrode at a much higher rate [48]. WebGalvanic corrosion will occur when cathodic and anodic metals are in contact in humid, salty, or outside environments, or in and around water systems. The potential for different metals to be an anode verses a cathode is listed in Table 1.
