Whisker toughened zirconia ceramic and preparation method thereof
The invention discloses whisker toughened zirconia ceramic and a preparation method thereof. The whisker toughened zirconia ceramic comprises a zirconia ceramic matrix, whiskers and a toughening layer arranged on the surfaces of the whiskers, wherein the toughening layer is a single interface layer with uniform components or a composite interface layer with multiple components, and the components of the toughening layer comprise one or more selected from Si3N4, BN nitride, SiC carbide and graphite. According to the invention, an interface layer inactive in reaction with zirconia ceramic is designed through a special interface layer preparation process, so the problem of secondary sintering reaction between the oxide whiskers and the zirconia ceramic matrix is solved; and the application scope of the whisker toughened zirconia ceramic is wide, and the whisker toughened zirconia ceramic is worthy of vigorous popularization.
本发明公开了一种晶须增韧氧化锆陶瓷及其制备方法，包括氧化锆陶瓷基体、晶须以及设置于所述晶须表面的增韧层；所述增韧层为均匀组分的单一界面层或为多种成分的复合界面层，所述增韧层的成分包括Si3N4、BN氮化物、SiC碳化物、石墨中、的一种或者多种。本发明通过特殊的界面层制备工艺设计了与氧化锆陶瓷反应不活跃的界面层，从而解决了氧化物晶须与氧化锆陶瓷基体产生二次烧结反应的问题；且应用领域广泛，值得大力推广。
