In this research, zirconia toughness alumina (ZTA) was produced by physical interaction between Al2O3 powder and Y2O3-ZrO2 powder. Two composition of powder with different Al2O3: Y2O3-ZrO2 ratio was used, 70:30 and 80:20 by weight. Two different compaction methods, i.e. uniaxial pressing and cold isostatic pressing (CIP) with a maximum load of 150 MPa were used in this research to investigate the differences in properties of composites. Sintering process was done at four different temperatures with the heating rate is 5 °C/ min with a soaking time of five hours. Mechanical testing, i.e. compressive strength and hardness was performed to all samples. The microstructure analysis using a Scanning Electron Microscope SEM was also studied. From the result, the composite with the ratio of 70:30 showed better mechanical properties as compared to 80:20 composite. Addition of zirconia in the composite gave an increased in toughness due to transformation toughening mechanism of tetragonal to monoclinic phase. As a conclusion the composites produced high compaction green density will improved the sintering process, resulting in improved mechanical properties 2014-03-10T09:16:27Z 2014-03-10T09:16:27Z 2013 Article Advanced Materials Research, vol. 740, 2013, pages 728-733 978-303785747-2 1022-6680 http://www.scientific.net/AMR.740.728 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32488 en Trans Tech Publications |
