The marine bio-fouling will quickly develop on the ship hull in a very short period as long as the hull has not a special treatment and immerses in the sea water. As the growth of marine organisms, the hull surface which attached these organisms will have the relevant physical and chemical changes. The change will cause the material corrosion and reduce the life of sea water cooling system in the ship. There are many ways to suppress the marine bio-fouling at present: the chlorination method generated by seawater electrolysis and the low voltage electrode method, etc., but they still have some disadvantages such as expensive, with low efficiency or polluting the environment.
The chlorination method is expensive and harm the environment, and the performance and the biological species of anti-fouling are also lower than the anti-fouling painting. The low voltage electrode method cannot only suppress the marine organism attachment, but also to prevent the hull corrosion. However it is still using the toxic elements in low-voltage electrode method at present. The study therefore choose environmentally friendly ruthenium-doped titanium substrate as a base material in the low-voltage electrode method. The coating process on the anode does not use toxic substances or gases, hence the mechanism of the anti-fouling is almost harmless to the environment. It can further implement energy saving and green manufacturing process. A little amount of bismuth and ruthenium are selected to manufacture the TiBiRu target, and using the TiBiRu target to produce a RuxBiyTiO2-xy film on the ITO glass and titanium plate. 19.5 sccm of argon and 0.5 sccm of oxygen will be introduced into a vacuum chamber in the sputtering process, and keep the sputtering pressure at 3.8x10-3 Torr with 120 minutes. The high energy ion generated by plasma will bombard the target surface with negative charge, and the target particle will deposit toward the direction of the substrate and forming a thin film. The result shows that it can manufacture a successful specimen under above conditions.
The resistance will be measured by a four-point probe in next stage, and measure the electrochemical parameters of the specimen: to determine the optimal voltage in the sea water by measuring the voltage of the hydrogen of catalyst. Finally, the surface microstructure of specimen will be observed by using a scanning electron microscopy (SEM) for confirming its film surface microstructure in line with our expectation.
