Silicon carbide whisker toughened aluminum oxide ceramic arm and preparation method thereof
The invention discloses a silicon carbide whisker toughened alumina ceramic arm and a preparation method thereof.The preparation method comprises the steps that alumina powder, silicon carbide whiskers, a dispersing agent and water are weighed, mixed and subjected to ball milling, slurry is obtained, spray granulation and drying are conducted, composite powder is obtained, the composite powder, water and a binder are stirred into pug, the pug is subjected to secondary mixing, and the silicon carbide whisker toughened alumina ceramic arm is obtained. The method comprises the following steps: printing a ceramic arm on a mold core to obtain printing pug, carrying out DIW-3D printing on the printing pug to obtain a half of a ceramic arm wet blank, printing the mold core with an air passage shape on the wet blank, continuously printing the other half of the ceramic arm to obtain a ceramic arm wet blank, and carrying out baking, sintering and fine processing to obtain the ceramic arm. The prepared ceramic arm has excellent mechanical performance, anti-static performance, heat-conducting performance and corrosion resistance, can adapt to various environments and is long in service life, the preparation method is simple, and the cost is low.
本发明公开了一种碳化硅晶须增韧氧化铝陶瓷手臂及其制备方法，该制备方法包括称取氧化铝粉、碳化硅晶须、分散剂和水混合球磨，得到浆料，经喷雾造粒和干燥，得复合粉体，将复合粉体、水和粘结剂搅拌成泥料，将泥料进行二次混炼，得到打印泥料，将打印泥料进行DIW‑3D打印，得到一半陶瓷手臂湿坯，然后在湿坯上打印具有气道形状的型芯，再继续打印另一半陶瓷手臂，得到陶瓷手臂湿坯，经烘烤、烧结、精细加工，即得陶瓷手臂。本发明制备的陶瓷手臂具有优异的机械性能、防静电性能、导热性能和耐腐蚀性能，可适应多种环境且使用寿命长，制备方法简单且成本低。
