Engineering the Composition Profile in Functionally Graded Materials Processed by Electrophoretic Deposition
Electrophoretic deposition (EPD) allows the formation of functionally graded materials (FGM) by depositing powder from a suspension to which a second suspension is continuously added during the process. The deposition yield is described as a function of time and starting composition of the suspensions, resulting in a model of the EPD process that allows the composition gradient in the green deposit as well as in the sintered material to be predicted. The model developed enables to calculate the composition gradient in the FGM material from the starting composition of the suspensions, the EPD operating parameters and the powder-specific EPD characteristics. The model was verified for the ZrO2-Al 2 O 3 system. Because of the excellent correlation between the predicted and the measured concentration profiles, the described model allows to precisely engineer and design the composition profile in FGM materials produced by EPD.
