Abstract : A series of experiments is described which was designed to obtain the electrochemical efficiency, electrochemical potential, and current output versus time data for five proprietary aluminum alloys using full-size anodes in sea water under conditions which approach those encountered in service. High and dependable electrochemical efficiency, sustained current output versus time characteristics, and elimination of inherently high resistance between cast-in steel cores and the anode metal must be realized before aluminum anodes can be considered for general Navy use.
