Effect of Voltage and Suspension Medium on Titania (TiO2) Film Prepared by Electrophoretic Deposition (EPD)
The electrophoretic deposition (EPD) technique was applied in order to produce titanium dioxide (TiO2) coating on stainless steel. Voltages of 2V, 4V, 6V and 8V and two types of TiO2 suspensions; (i) acidic (pH 4) and (ii) alkaline (pH 8) were used. Depositions were carried out for duration of 10 minutes. The TiO2 coatings phases, morphologies, thicknesses and weight were analysed. It was found that thickness and weight of coatings produced using both acidic and alkaline TiO2 suspensions increased proportionally. However, from the uniform and dense morphology of coatings, acidic TiO2 suspension was observed to yield better TiO2 depositions through the EPD technique.
