Abstract:
Metal matrix piezoelectric composites have been developed to improve strength of piezoelectric ceramics. This composite is fabricated by embedding piezoelectric ceramics with surface-oxidized metal-core in metal matrix. However, when composites are polarized, the oxide film on the metal-core absorbs the electric field, which lowers the electric field applied to the piezoelectric ceramics and inhibits polarization. In addition, there is a possibility of dielectric breakdown of the oxide film of the metal-core when an electric field is applied. The breakdown electric field and permittivity of the oxide film were measured, and the obtained data were applied to a series capacitor model to optimize the polarization conditions. Measurements of oxide film data for Ni and Ti, the candidate materials for the metal-core, revealed that the average values of the breakdown electric field and permittivity were 16.88 kV/mm and 9.637 for nickel and 2.610 kV/mm and 85.49 for titanium, respectively. The obtained data were applied to series capacitors model, however it was not possible to obtain a polarized electric field above 0.3 kV/cm and below the breakdown electric field of the oxide film. Therefore, it proved difficult to optimize the polarization conditions by optimizing the Ni and Ti oxide films
