Outline of Final Research Achievements

In this study, the fabrication process ofa functionally graded piezoelectric material by using the electrophoretic deposition (EPD) was established. The bilayer lead zirconate titanate (PZT) piezoelectric ceramic material was fabricated by applying this process and its characteristics were evaluated. The results obtained are as follows. In EPD, amount of deposition per hour depend on the pH of suspension. It was clarified that the optimal pH is about 5 in deposition of PZT. Measuring fracture toughness of the PZT ceramics made by this process showed that the fracture toughness in the direction of deposition is about 50 % lower than that in the deposition surface, so there is strong anisotropy of strength in the material by using EPD.
