Galvanic action table
WebTable 2 presents the ranking of metals based on their electrical potential from anodic (least noble) to cathodic (most noble). The farther apart two metals are in the table, the more severe and faster the galvanic attack. … The Galvanic Series, also called the electro-potential series, lists metals in the order of their nobility. (Noble metals are those that are resistant to corrosion and oxidation.) When two metals are immersed in an electrolyte, while also being connected externally by a conductor, the less noble metal … See more Professor Luigi Galvani first demonstrated the presence of electric current in animal tissue. Alessandro Volta, another scientist, verified Galvani’s experiments, and coined the term ‘galvanism’, … See more In general, the farther apart the metals are in the galvanic series, the greater is the corrosion when used together. The galvanic series applies to a specific electrolyte solution – in other words, for each electrolyte that … See more The key to avoiding damaging reactions from different combinations of metals is by using metals that are near to each other in the galvanic series. However, there might be instances during … See more The table below is the galvanic series of metals, alloys and graphite in seawater (most noble at top) in flowing seawater, at ‘normal’ temperature. Maximum recommended voltage difference is 0,2V: Note that graphite, … See more
