Notes:
AlN-ZrO2 composites were prepared by solid state reaction in N2 atmosphere at 1500°C for 4hwith PSZ and Al powders as raw materials. Effects of Al content on performance of the composites andthe process of nitriding reaction were investigated. The results showed that surface layer reaction ofsamples happened between 450°C and 765°C, and diffusion reaction happened between 765°C and1500°C. With increasing of Al content, thermal expansion coefficient decreased, bending strengthincreased, thermal shock resistance and oxidization resistance were improved. Finally, bending strengthof 73.61 MPa and thermal expansion coefficient of 6.06×10-6 /°C were realized for AlN-ZrO2 composites
