摘要
Abstract
In this paper， ZrO2/Al2O3 ceramic composites were prepared with Al2O3 powder made by thermal decomposition and (Y,Ce)-ZrO2 by coprecipitation as raw materials by means of appropriate technique.It was found that the grain growth of zirconia was inhibited with the introduction of alumina,which resulted in higher strength and toughness of the ceramics.When the addition of alumina was 30wt%,the bending strength and fracture toughness of the composites were 986MPa and 13.7MPa*m1／2 respectively.The mechanical property was improved by the dispersion toughening of alumina grain and the phase transformation toughening of zirconia.关键词
