Yttria-stabilized zirconia(YSZ)/Al2O3 micro-laminates with layers as thin as 2μm and a total of >100 layers were fabricated by electrophoretic deposition (EPD). Positively charged powders were deposited on a cathode, layer by layer from 2.5 v/o solids/ethanol suspensions using constant current. The suspensions were characterised by pH, conductivity and rate of deposition. System explored have been ZrO2/Al2O3, ZrO2/Al2O3/La-Aluminate, ZrO2/Al2O3/Al2O3-fibres and combination of these phases including functionally-gradiented layers. The microstructures of the sintered, theoretically dense samples were characterized by optical and electron microscopy, and microindentation was used to explore crack/layer/interfacial interactions.
