Abstract

Composite ceramics between Al2O3 (6 mol% MgO); AM and ZrO2 (4 mol% Y2O3); ZY with 40:60, 50:50, and 60:40 ratio were prepared. The samples were sintered under different sintering method between normal sintering and two-step sintering method. The effects of the different contents of AM and ZY and sintering condition on the structural analysis, densification, microstructure and mechanical behavior were studied. It was found that composites with higher proportions of ZrO2 showed higher weight percentages of t-ZrO2 and c-ZrO2 phases which is obtained high density and good mechanics properties. The Fracture toughness mechanisms of composites are also discussed in detail around the sintering parameters. The AM:ZY composite ceramics that provides good mechanical properties were revealed in both sintering method in optimum conditions.


Keywords: Al2O3, ZrO2, Composite, Ceramics, Sintering.
