IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM EMPLOYING COBALT SPINEL STRUCTURED ANODE

摘要

Impressed current cathodic protection systems employing an anode having a cobalt spinel type surface, said surface having the formula: MxZyCo(3-(x+y))O4, where M is a metal or a mixture of two or more metals selected from the group of metals contained in Groups IB, IIA, and IIB of the periodic table of the elements, where Z is a metal or a mixture of two or more metals selected from the group of metals contained in Group IA of the periodic table of the elements, where 0 < x < 1, where 0 < y < 0.5, and where 0 < (x + 2y) < 1.
