摘要
陶瓷的韧性是陶瓷材料研究领域的核心问题 ,氧化铝陶瓷材料的脆性极大地限制了该项材料的推广应用 .为了减小Al2 O3 基陶瓷材料的脆性 ,除了采用先进的制备工艺外 ,人们研究了许多增韧的手段 :氧化锆相变增韧 ;纳米技术增韧 ;晶须和纤维增韧 ;颗粒弥散增韧 ;复合增韧 ;表面改性增韧等 ,详细探讨了近年来氧化铝陶瓷材料的增韧研究现状和今后的发展方向 .
The toughening of ceramics is a pivotal issue in the field of ceramic material. However, the brittleness of alumina ceramic material limits the application of the material remarkably. In order to decrease its brittleness, many toughening methods are adopted, besides the advanced manufacturing technology. These methods include ZTA (the zirconia transformation toughening), nanometer technology toughening, whisker and fiber toughening, particle dispersion toughening, combined toughening, surface modification toughening, etc. The article detailedly discusses the present status and developing direction of toughening research on alumina matrix ceramic material.
