ABSTRACT:
Non self-passivating cathodic protection anode materials such as graphite and high silicon iron are treated to improve corrosion resistance. Anodically stable oxide coatings such as cobalt oxide (cobalt spinnel) or precious metal oxides are received on the underlying anode substrate. The rate of consumption of the anode material during the operation of the cathodic protection system is dramatically reduced.
