Paper Title:
Preparation and Performance of AlN-ZrO2 Multiphase Material
  Abstract

AlN-ZrO2 composites were prepared by solid state reaction in N2 atmosphere at 1500°C for 4h with PSZ and Al powders as raw materials. Effects of Al content on performance of the composites and the process of nitriding reaction were investigated. The results showed that surface layer reaction of samples happened between 450°C and 765°C, and diffusion reaction happened between 765°C and 1500°C. With increasing of Al content, thermal expansion coefficient decreased, bending strength increased, thermal shock resistance and oxidization resistance were improved. Finally, bending strength of 73.61 MPa and thermal expansion coefficient of 6.06×10-6 /°C were realized for AlN-ZrO2 composites.
