Abstract
Nanograined yttrium-stabilized ZrO2/Al2O3 composites were fabricated by a pulse electric current sintering (PECS) method. The starting powders with sizes less than 10 nm were successfully synthesized by the chemical process. The composites sintered at temperatures above 1300°C showed the relative density above 98%. Examination by transmission electron microscopy (TEM) showed that the yttrium-stabilized ZrO2/10 mol% Al2O3 composite consisted of the homogeneous and very fine matrix grains with sizes less than 100 nm.
