Development of Advanced Zirconia-Toughened Alumina Nanocomposites for Orthopaedic Applications

摘要

Current ceramic solutions for orthopaedic applications are nowadays questioned. Great concern is rising for thermal stability problems of zirconia containing ceramics. Thus new zirconia containing composites are developed today. Properties of advanced zirconia-alumina nanocomposites is presented here. The use of a colloidal processing route allows to get a very fine distribution of zirconia grains within the matrix. By tailoring the microstructure, it is possible to get better mechanical properties without any thermal degradation sensitivity.
