摘要
The influence of the material's electrical properties on the pulsed electric current sintering (PECS) behavior of Y-ZrO(2) based ceramic composites is investigated in detail. The current and temperature distributions in the sintering compacts are investigated, using a developed finite element code, and their influence on the densification behavior is highlighted. Both zirconia ceramics and zirconia based ceramic composites with improved mechanical properties, as compared to traditionally hot pressed ceramics, could be obtained by PECS.
