Electrophoretic deposition (EPD) is an attractive forming process to fabricate plate shaped binary functionally graded materials (FGMs) from suitable stable suspensions. In the present work, the capability to produce Al2O3 and ZrO2 functionally graded bulk material by means of EPD from a non?aqueous stable suspension based on 2?butanone, n?butylamine and cellulose nitrate solution is presented. The EPD processing parameters and sintering are described, and the density of the FGM composite, hardness, toughness and residual stresses are measured using indentation methods on cross?sections of the sample. Scanning electron microscopy confirmed that the sintered body is an FGM.
