Not only efficiency of chlorine evolution reaction (CER) but also durability namely service life is very important property in dimensional stable anode for Ballast Water Management System (BWMS) for marine ships. Many researchers have been focused on improving efficiency of CER by controlling composition, phase and surface area for a long time, but the efforts to increase durability was relatively small. In this study, we have investigated the effect of TiO₂ protective interlayers on efficiency and durability of DSA electrodes. TiO₂ protective interlayers were prepared by thermal oxidation at 500, 600 and 700℃ on Ti substrate. And then the DSA electrodes consisting of Ti/RuO₂-PdO-TiO₂ were prepared by thermal decomposition method on TiO₂ interlayers. The efficiencies of CER of DSA electrodes without TiO₂ interlayer and with TiO₂ interlayer grown at 500, 600 and 700℃ were 94.19, 94.45, 84.60 and 76.75% respectively. On the otherhand, durabilities were 30, 55, 90 and 65 hours respectively. In terms of industrial aspect, the performance of DSA is considered high efficiency and durability which can correspond to total production of chlorine. If we considered the performance index of DSA as the product of efficiency and durability, performance indices could be recalculated as 28.26, 50.85, 76.14 and 49.89 respectively. As the thermal oxidation temperature increasing, life time were increased remarkerbly, while efficiency of CER was decreased slightly. As a result, DSA electrode with TiO₂ interlayer grown at 600oC has shown about 2.7 times performace of original DSA electrode without TiO₂ interlayer.
