This study investigated the electrochemical properties of Dimensional Stable Anode (DSA) and titanium nitride (TiN) films of two electric catalyst, The use of low-voltage electrode fouling systems to alternating current voltage suppression sea creatures attached to the hull. DSA has a very low consumption rate, good electrical conductivity, corrosion resistance and electrochemical anode catalyst properties. And a titanium nitride (TiN) having a low resistivity and high chemical stability, and therefore has high hardness, high thermal conductivity, high abrasion resistance and other advantages. Electrical catalyst film applied hydroxyl radical (OH-) electron transfer and catalytic alternating the use of low voltage direct current generated by the destruction of marine life living organisms depend, therefore can effectively suppress parasitic microorganisms film; same time, the electrode surface can be pushed away from the body, so that the surface of the electrodes to maintain the effectiveness of the original sea creature can not be attached and generation. In this study, the first measurement of the electrical DSA catalyst with hydrogen TiN voltage different from the voltage value of the hydroxyl radical was observed (OH-) of the variations to determine the optimum voltage value of the field of seawater tests. It was found that long TiN surface pitting circumstances, while DSA no case of any corrosion or stripping. TiN surface pitting should be prolonged under the current actuator, electronic effects due to fall off due to the reduction of Ti. So use DSA seawater test site within Kaohsiung to homemade monitoring equipment records and adjust the applied voltage and the polarity switch, after a preliminary field test four weeks seawater discovery, DSA electricity catalyst control specimen surface has not energized ray tube with a small amount of seaweed attached, while the control group plus DSA electricity catalyst specimen surface is quite clean and low-voltage display DSA has the potential to prevent hull fouling. Currently, long live the sea DSA test continued progress, and TiN pitting and antifouling feasibility further confirmation.
