Research Abstract

A composite made of nanometer-sized ceria-stabilized zirconia/alumina has recently been developed. It is reported that this new material is comparable in strength and toughness to metal, taking advantage of the characteristics of both zirconia and alumina.
At the same time, the electrophoretic deposition (EPD) method has become widely used for ceramic processing and this method would seem to make it possible to fabricate a dense, uniform framework even in a complicated shape. Therefore, if the aforementioned ceria-stabilized zirconia/alumina nanocomposite can be deposited successfully using the EPD method, an excellent framework would be fabricated more easily and completed in a shorter time.
The aim of this study was to evaluate the electrophoretic deposition (EPD) behavior of ceria-stabilized zirconia/alumina (Ce-TZP/Al_2O_3) granulated powder. Two types of slurry with a powder to solvent ratio of 10wt% and 20wt% were used. The zeta potential of the slurry was measured using the spectrometer at different pH levels. Then, EPD was performed to measure the weight of the deposited particles at varying pH levels, at two voltages (50V and 100V). The isoelectric point of the Ce-TZP/Al_2O_3 mixed powder was close to a pH of 8.5. If EPD was performed, the deposition of ceramic particles was observed in the range of pH3 to pH7 and the greatest deposition was found at around pH7. The deposition of ceramic particles was increased when the slurry concentration and voltage were high.
