Marine Corrosion Studies: Characterization of the Corrosion Behavior and Response to Cathodic Protection of Nineteen Aluminum Alloys in Sea Water

摘要

The corrosion characteristics of nineteen structural aluminum alloys were studied in quiescent sea water. Some alloys were exposed with and without cladding, and others at more than one strength level for a total of twenty-six material conditions. The response to cathodic protection of all the alloys studied was also determined. The electrochemical potentials of the alloys were monitored during the experiment and a relationship was developed between the electrode potential and the corrosion characteristics of the alloys.
