Summary

Fully dense Al2O3-ZrO2 nanostructured composites were fabricated by a pulsed magnetic compaction and conventional sintering of the nano-sized powders. Two different approaches have been applied for production of the composite powders. Powders of the first group were prepared by mixing in the iso-propanol of a pure Al2O3 powder produced by electrical explosion of wire, and a Y2O3-stabilized ZrO2 produced by pulsed laser vaporization of target. Powders of the second group were prepared by pulsed laser evaporation of targets comprising mixtures of coarse Al2O3 and 1.6YSZ particles. This treatment caused formation of nano-sized particles in largely metastable states: amorphous Al2O3 and Al2O3-Y2O3-ZrO2 solid solutions. The sintered composite from the first group containing nearly equal volume fractions of Al2O3 and 2.8YSZ phases 70 and 140 nm in size respectively proved to be the best. It was characterized by the maximum density and bending strength.
