MICROSTRUCTURAL DESIGN OF BIOINERT COMPOSITES IN THE ZrO_2-Y_2O_3-CeO_2-Al_2O_3-CoO SYSTEM

摘要

It is shown that a scientifically sound approach to each stage of producing ZrO_2-based bioinert implants (from the synthesis of starting powders to their sintering) is a necessary condition for promoting the optimum structure and high mechanical properties. Conditions for producing bioinert implants with regular, laminar, and highly porous microstructures are found. The research results serve as a scientific basis for microstructural design of various bioinert implants in the ZrO_2-Y_2O_3-CeO_2-Al_2O_3-CoO system.
