Abstract
Electrophoretic deposition (ED) was used to form uniform–structure green bodies with a thickness of about 3 mm of SiC whisker–tetragonal zirconia polycrystals (TZP) mixtures. A kinetic model for ED is presented. The model predicts the decrease of the forming rate as an exponential function of time. Diagrams of colloidal groups and electrochemical reactions of charged solid particles on the deposited electrode are proposed. The effects of applied electric field, viscosity, dielectric constant, amount of suspending agent, and zeta potential of the solid particles in Al(OC3H7)3–C3H7OH–CH3OH sol on ED processing are discussed.Keywords
