Abstract |
This study is for developing a system for electro-deposition utilizing sea water containing various ions like calcium and magnesium. This is the first step research for the final goal which is a development of anti-corrosive steel for RC structure, so that this paper is mainly focused on the development for electro-deposition system. Optimum conditions for steel coating is obtained through various tests considering anode type, temperature, duration time, and current density. The composition of electro-deposition is analyzed through SEM, EDS, and XRD and it is evaluated to be CaCO3 and Mg(OH)2. Through measuring polarization potential and current density in the coated steel, the coating layer from the developed system is evaluated to have high resistance to steel corrosion. Additional tests and discussions on durability and structural performance in the coated steel from this work will be performed for the second step research.
