通过优化工艺参数，重点改善和控制细晶粒生长，并通过胶体加工形成致密的理想微观结构，制备了新型 Al2O3-ZrO2 复合材料。电声技术用于在线控制高浓度悬浮液的稳定性。结果表明，制备的致密均匀细晶 Al2O3-ZrO2 复合材料的起始粉末特性、流变性能、烧结和微观结构之间存在良好的相关性 (C) 2008 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
A new type of Al2O3-ZrO2 composite was fabricated by optimizing processing parameters with emphasis on improving and controlling fine grain growth and the formation of compact desirable microstructures by using colloidal processing. The electroacoustic technique was used for on-line control of the stability of highly concentrated suspensions. The results gave good correlation between starting powder characteristics, rheological properties, sintering and microstructure of fabricated dense and homogeneous fine-grained Al2O3-ZrO2 Composites (C) 2008 Acta Materialia Inc.
