Preparation method of wear-resistant ceramic and product thereof
The invention belongs to the technical field of wear-resistant ceramics, and particularly relates to a preparation method of wear-resistant ceramics and a product thereof. The preparation method comprises the following steps: (1) weighing TiC powder, W powder, Mo powder, Zr powder, Hf powder and Si powder according to a certain molar ratio, and then putting the weighed raw materials into a ball milling tank for ball milling, (2) after ball milling is finished, drying the obtained mixed material, then adding a polyvinyl alcohol aqueous solution with the mass fraction of 5% for granulation, and (3) drying the dried mixed material to obtain the TiC-W-Mo-Si composite material. The granulated powder is preformed through a tablet press and then pressed into a blank, the obtained blank is degummed in a muffle furnace, then sintered, subjected to heat preservation treatment at a certain temperature and cooled to the room temperature along with the furnace, and the ceramic is obtained. The hardness Hv of the wear-resistant ceramic ranges from 14.5 GPa to 15.4 GPa, the bending strength ranges from 460 MPa to 480 MPa, and the wear rate ranges from 3.1 * 10 <-5 > to 3.5 * 10 <-5 >. The preparation method is simple, the performance is excellent, and the material is an ideal material for practical application.
本发明属于耐磨陶瓷技术领域，具体涉及一种耐磨陶瓷的制备方法及其产品。所述制备方法包括以下步骤：(1)将TiC粉、W粉、Mo粉、Zr粉、Hf粉和Si粉按照一定的摩尔比称取，然后将称取的原料放入球磨罐中进行球磨，(2)球磨结束后，将得到的混合物料进行干燥，然后加入质量分数为5％的聚乙烯醇水溶液造粒，将造粒的粉体通过压片机预成型后再压制成胚体，将所得的胚体在马弗炉中排胶，然后于烧结，然后在在一定温度下保温处理，然后随炉冷却至室温得到陶瓷。所述耐磨陶瓷的硬度Hv为14.5～15.4GPa，抗弯强度为460～480MPa，磨损率为3.1×10‑5～3.5×10‑5。本发明的制备方法简单，性能优异，是用于实际应用的理想材料。
