| 摘 要： | 本文介绍了用CO_2激光合成Al_2O_3、Al_2O_3-5％mol Cr_2O_3固熔体,Al_2O_3-20％wtZrO_2(+3％molY_2O_3)混合体和Al_2(WO_4)_3陶瓷材料的方法。激光合成的Al_2(WO_4)_3为Al_2O_3-WO_3二元平衡相图中不存在的新化合物。对激光合成的陶瓷材料进行了组织形貌分析,并测量了其显微硬度,发现用激光合成的陶瓷较用昔通工艺制备的同种陶瓷有更高的硬度。

| Abstract: | In this paper, A12O3, Al2O3-5%mol Cr2O3 and Al2O3-20%wt ZrO2 powders have been sintered to fabricate oxide ceramics with CO2 laser. The product of Al2(WO4)3 is-found as a new compound which can not be found in two-diminsional equilibrum phase-diagrams. The analysis of microstructure and hardness of the laser synthesized materials have been conducted. The hardnesses of laser synthesized materials are shown to be higher than that produced with the conventional sintering mothed in furnace. |
