Preparation method of toughened aluminum oxide ceramic body
The invention discloses a preparation method of a toughened aluminum oxide ceramic blank. The preparation method comprises the following steps: s1, preparing a toughening material; s2, preparing a ceramic material; s3, carrying out compression molding and mixing work; s4, carrying out segmented drying treatment; s5, performing sintering treatment in a manner that the continuous fiber preformed blank is placed on molten metal, the molten metal permeates into a preformed body due to the capillary action, the preformed body is in the air or oxidizing atmosphere, and the compact continuous fiber reinforced ceramic matrix composite containing a small amount of residual metal is formed; s6, injecting nano-cellulose into a fiber reinforced ceramic matrix composite material, carrying out pressing treatment by adopting an external pressing forming device, effectively controlling the pressing duration and the pressing weight, mixing raw materials, and carrying out precipitation screening to obtain the nano-cellulose. Herein, the nanocellulose is added into the formed blank, so that the overall toughness of the blank is improved, and a relatively high toughness effect is achieved.
本发明公开了一种增韧氧化铝陶瓷坯制备方法，包括以下步骤：S1、增韧材料制备；S2、陶瓷材料制备；S3、压制成型混合工作；S4、分段干燥处理；S5、烧结处理工作，将连续纤维预成型坯件置于熔融金属上面，因毛细管作用，熔融金属向预成型体中渗透，并处于空气或氧化气氛中，形成含有少量残余金属的、致密的连续纤维增强陶瓷基复合材料；向纤维增强陶瓷基复合材料内部注入纳米纤维素并采用外部的压制成型装置进行压制处理工作，并对压制时长以及压制重量进行有效把控，再通过原料混合工作再进行沉淀筛选工作提取得到纳米纤维素，通过将纳米纤维素添加到成型坯件内，从而提升坯件的整体韧性，达到较强的韧性效果。
