Synthesis of Al2O3-ZrO2 Nanocomposite by Mechanical Activated Self-propagating High Temperature Synthesis(MASHS) and Ignited via Laser |
|
| چکیده انگلیسی مقاله |
By consideration of unique properties of composite Al2O3-ZrO2 such as high toughness, high wear resistant and relative low thermal expansion, in this study, nanocomposite of Al2O3-ZrO2 was produced by Mechanical activated Self propagating High-temperature Synthesis (MASHS) using laser beam for ignition. First Al and ZrO2 powders were mixed in the mole ratio of 1:1 and milled for 1, 3 and 6 hours. Then the mixtures were pressed and were exposed by continuous wave (CW) CO2 laser for starting combustion reaction. To find the specifications of the products X-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy-Dispersive X-ray spectroscopy (EDX) were used. The XRD results show that samples have α-Alumina and also cubic and monoclinic phases Zirconium oxides together. The dendrite structures were formed during the process. |
