... ABSTRACT Indium-activated aluminum anodes have been selected as potential candidates to replace current military specification (MIL-A-18001J) zinc anodes for the cathodic protection of Navy ships. One concern regarding the use of indium-activated anodes is the anode performance in cold (40°F...

..., an optimum CP design using sacrificial anodes is achieved by inducing a high current density (e.g., 320 mA per square meter in the southern North Sea) on steel immediately upon immersion to promote rapid cathodic polarization and formation of high quality calcareous deposits (B78, A13, B68, A48). The well...
