Summary

The mechanical properties of ceramics can be improved by the addition of toughening material. Computed gamma-ray tomography and neutron diffraction are two possible methods for evaluating the effects of the toughening process. In this study, samples of zirconia pellets toughened with alumina were prepared and then examined using both techniques. The toughening was performed by the “infiltration” of green zirconia with aluminum nitrate, followed by firing during which alumina was formed. The concentration and distribution of alumina in sintered zirconia pellets were measured. The results obtained for pellets prepared with different infiltration times are discussed.
