Superplastic deformation of Zirconia-Alumina composite fabricated via layer by layer method

Abstract

The layer by layer (LBL) method will be the most efficient techniques to prepare well-dispersed nanocomposite powders. The LBL method has been established to produce several types of functional ceramics as one of the simplest and the most versatile processing techniques for fabricating nanocomposite powders. In this study, ZrO2- Al2O3 nanocomposite particles were synthesized by coating nano- Al2O3 sol on the surface of ZrO2 particles to produce a well-dispersed ZrO2- Al2O3 composite by adopting the layer-by-layer (LBL) technique. As a result the superior microstructure and mechanical characteristic of 3Y-TZP based Al2O3.
