4.3.1 One type of Galvanic Series lists the metals of interest in order of their corrosion potentials, starting with the most active (electronegative) and proceeding in order to the most noble (electropositive). The potentials themselves (versus an appropriate reference half-cell) are listed so that the potential difference between metals in the series can be determined. Corrosion is the gradual destruction of a metal by chemical or electrochemical means. The most generic form of corrosion is galvanic corrosion. A combination of a cathode, an anode, and an electrolyte must be present for this type of corrosion to occur. This combination of cathode, anode, and electrolyte is called a galvanic cell.

Contact ASTM International (www.astm.org) for the latest information. The galvanic series determines the electrochemical potential and nobility of metals and metal alloys. Each alloy or metal has a distinctive corrosion potential. The more negative a metal or alloy is, the more likely it is to suffer galvanic corrosion. When two metals are submerged in an electrolyte, while also electrically connected by a Der Rahmenlehrplan gilt für Schülerinnen und Schüler, die ab dem Schuljahr 2018/19 in die Einführungsphase an Gesamtschulen und beruflichen Gymnasien eintreten und ab dem Schuljahr 2019/20 in die Qualifikationsphase der gymnasialen Oberstufe eintreten oder die-se aus anderen Gründen beginnen.
