Paper Title:
Mechanical Properties of Alumina/Zirconia Functionally Graded Material Prepared by Electrophoretic Deposition
  Abstract

The mechanical properties of a quasi-symmetrical planar functionally graded material (FGM) of Al2O3 / Al2O3+20%ZrO2 / Al2O3+5%ZrO2 prepared by electrophoretic deposition and pressureless sintering has been studied. Hardness and fracture toughness were measured using indentation methods on cross sections of samples. From the difference between lengths of cracks parallel and perpendicular to layers the residual stresses (arisen due to the thermal expansion coefficient mismatch) were calculated, their profile along the cross section has been estimated and compared with values obtained using a finite element model.
