The aim of this work was preparation of alumina laminates and fibre reinforced alumina containing zirconia micro-fibres inside the inter-layer interface. Electrophoretic deposition was performed from concentrated isopropanolic suspensions stabilised by monochloracetic acid containing mixture of alumina powder and certain amount of zirconia micro-fibres. A method for in-situ monitoring the deposition of alumina and zirconia particles and fibres mass was applied to control deposition kinetics. Two different approaches for composite deposition were applied: i) electrophoretic deposition of powders mixture and ii) electrophoretic deposition from milled suspension containing stabilization aid. Applying the optimised procedure the alumina laminates reinforced with zirconia fibres were prepared. The fibres located in the interlayer boundary affected dramatically the fracture response of these materials.
