Preparation method of high-strength wear-resistant ceramic material
The invention relates to a preparation method of a high-strength wear-resistant ceramic material, and belongs to the technical field of ceramic material preparation. The preparation method comprises the following steps: firstly, by taking expanded graphite as a template, electroplating a metal aluminum layer on the surface of the expanded graphite through a metal salt electroplating method, and then putting the electroplated expanded graphite into a sintering furnace for sintering, so that the expanded graphite template is sintered and removed, and the hollow layered aluminum oxide powder withan expanded graphite-like structure is obtained; taking the hollow layered aluminum oxide powder as a self-made wear-resistant material and adding the powder into a ceramic material, taking rice husks as a raw material, carrying out microbial fermentation to slightly corrode the rice husks to generate abundant pores, carbonizing the slightly-corroded rice husks to obtain carbides, mixing the carbides with hydrogen-containing silicone oil, and reacting active hydrogen and a large amount of methyl groups of the hydrogen-containing silicone oil on the surface of the carbonized rice husk powder,and forming silicon carbide whiskers with high specific surface area under a high-temperature condition. The ceramic material is prepared by blending the self-made wearing-resistant material, the self-made reinforcing material, the aluminum oxide and the sintering aid, so that the ceramic material has a wide application prospect.
本发明涉及一种高强度耐磨陶瓷材料的制备方法，属于陶瓷材料制备技术领域。本发明首先以膨胀石墨为模板，通过金属盐电镀法在膨胀石墨表面电镀一层金属铝层，再将电镀后的膨胀石墨放入烧结炉中烧结，使得膨胀石墨模板烧结去除，从而得到具有类膨胀石墨结构的中空层状氧化铝粉末，用此作为自制抗磨功能料添加进陶瓷材料中，还以稻壳为原料，首先通过微生物发酵使得稻壳微腐产生丰富的孔隙，再将微腐后的稻壳炭化制得碳化物，将碳化物和含氢硅油混合，利用含氢硅油的活泼氢和大量甲基作用于炭化稻壳粉表面，在高温条件下形成高比表面积的碳化硅晶须，通过自制抗磨料和自制增强料和氧化铝以及烧结助剂共混制备得到陶瓷材料，具有广阔的应用前景。
