摘要：
Alumina-zirconia nanopowder mixtures of different composition were produced by laser ablation from micropowder pellets followed by condensation of the induced vapour in a controlled aggregation gas. The employed laser was a pulsed 1000 W Nd:YAG-laser. The median particle diameter of the produced nanopowder was about 13 nm. Nanopowders of different composition were consolidated and sintered under various temperature conditions. The sintered composites were investigated regarding density and hardness. In order to investigate the coarsening of the nanostructure, the grain sizes of the composites were determined by scanning electron microscopy.
