In natural seawater, pure aluminum develops oxide layer which forms a barrier, protecting against corrosion. Alloying with other elements prevents the development of oxide layer by introducing localized galvanic cells. Different aluminum alloys exhibit different electrochemical behavior. The scope of the project was to study the electrochemical behavior of different chemical composition of aluminum...

During the 2005 National Electrical Codereg (NECreg) review cycle, a relatively simple revision was made that will have a significant impact on the cathodic protection systems of petroleum and chemical facilities (plants) in the future. The 2005 NEC now makes it clear that there must be an interconnection of all concrete-encased steel reinforcing bar (rebar) to the facility grounding electrode system...
