MARINE CORROSION STUDIES: THE ELECTROCHEMICAL POTENTIAL OF HIGH PURITY METALS IN SEAWATER

A study was conducted in which the electrochemical potentials of high purity metals were determined in quiescent seawater. The data are presented as histograms and as potential time graphs. The electrochemical potentials of many of the metals varied over a broad range, and therefore it is impractical to assign a specific potential value to many of the metals. A galvanic series is included, however, based on the data obtained from the histograms. Two of the metals, bismuth and tin, had relatively stable potentials in seawater, but further experimentation indicated their unsuitability as reference electrodes to monitor cathodic protection systems on ship hulls.
