Carbon fiber mesh anode is used as an alternative of traditional anode material for cathodic protection system. Theoretical analysis of feasibility and preliminary experimental work of the new material is presented in this paper. Long-term exposure in marine environment has been simulated using an electrochemical acceleration method to shorten the experimental time. Treated specimens are examined by scanning electron microscope (SEM) and laser-ablation inductive-coupled-plasma mass spectroscopy (LA-ICP-MS) for microstructure study and chemical analysis. Preliminary results show a ring-pattern zone at anode adjacent area but no sign of damage at anode and anode adjacent area.
