Effect of Voltage and Suspension Medium on Stanum Oxide (SnO_2) Film Prepared By Electrophoretic Deposition (EPD)

摘要

The electrophoretic deposition (EPD) technique was applied in order to produce stanum oxide (SnO_2) coating on stainless steel. Voltages of 2V, 4V, 6V and 8V and two types of SnO_2 suspensions; (i) acidic (pH 3) and (ii) alkaline (pH 10) were studied. Depositions were carried out for duration of 10 minutes. It was found that weight of coatings produced using both acidic and alkaline SnO_2 suspensions increased proportionally with increasing voltage. However, the morphology of coatings in acidic SnO_2 was observed to yield better SnO_2 depositions through the EPD technique.
