Abstract
ZrO2-Al2O3 particulate composites were prepared by infiltration of pre -sintered alumina skeletons with a precursor of zirconia and subsequen t sintering at 1600 degrees C. The composite specimens exhibit a gradi ent in composition, the zirconia content being higher in the superfici al zones than in the core. The influence of the ZrO2 content on the vo lume fraction of t-ZrO2, the t-->m transformation temperature, and the microstructural development were studied.
