Preparation of alumina-zirconia composites containing microfibers

Popis výsledku v původním jazyce

The electrophoretic deposition (EPD) is a suitable shaping method for ceramic composites preparation from its early beginning. Preparation of particulate, fibre reinforced and laminate ceramic composites by EPD using either aqueous or inorganic solventswas successfully demonstrated [1-4].The aim of this work was preparation of alumina and zirconia laminates created from alternating composite layers containing alumina and zirconia micro fibres inside the layers and/or at the inter-layer interface. Electrophoretic deposition was performed from concentrated isopropanolic suspensions stabilised by monochloracetic acid containing mixture of alumina or zirconia powder and certain amount of alumina or zirconia micro fibres. Three methods of suspension preparation were studied from the point of view of micro fibre arrangement in the deposit. Firstly, the EPD was conducted using the suspension prepared from ball milled premixed micro fibre and powder dried granulate, secondly directly from the
