Elaboration and characterization of Ni/BaTiO 3 Functionally Graded Piezoelectric Material for active vibration control applications

Abstract : Ni/BaTiO 3 FGPM pellet has been elaborated by the Spark Plasma Sintering technique (Dr Sinter-Lab SPS-515S, SPS Sintex Inc.). SPS sintering consists of heating the sample very quickly while applying a uniaxial charge. Thus, it is possible to densify the material in very short time thus limiting both grain growing and the interdiffusion of different chemical species. We propose to sinter together layers of mixture of ceramic powder/ metal with compositions ranging from 100% ceramic to 100% metal. Powders were sintered in a 15 mm diameter graphite die with a constant applied pressure of 100 MPa. The heating rate was fixed to 50°C.min-1. The cooling rate was around 100°C.min-1 .
