High-toughness and high-hardness wear-resistant ceramic and preparation method thereof
The invention belongs to the field of ceramic preparation, and particularly relates to high-toughness and high-hardness wear-resistant ceramic and a preparation method thereof. The preparation method comprises the following steps: proportioning TiC powder, Mo powder, Sm powder, Ti powder and Si powder according to a certain proportion, and then carrying out ball milling treatment; after ball milling, adding carbon fibers and SiC whiskers, continuing ball milling, vacuumizing slurry obtained after ball milling, and performing heating and drying treatment; and mixing the raw materials, adding polyvinyl alcohol, granulating, pre-forming the granulated powder by a tablet press, pressing into a green body under 30-40MPa, degumming the obtained green body in a muffle furnace at 600-800 DEG C for 2-4 hours, sintering at 1500-1700 DEG C for 1-5 hours, and cooling to room temperature along with the furnace to obtain the ceramic. The high-toughness and high-hardness wear-resistant ceramic is rich in raw material resource, simple in preparation process and relatively low in production cost, and the obtained high-toughness and high-hardness wear-resistant ceramic has excellent wear resistance and also has relatively high hardness and toughness.
本发明属于陶瓷制备领域，具体涉及一种高韧性、高硬度耐磨陶瓷及其制备方法。将TiC粉、Mo粉、Sm粉、Ti粉和Si粉按照一定比例进行配料，然后进行球磨处理；球磨后，添加碳纤维和SiC晶须，继续球磨，将球磨后的浆料经抽真空后进行升温烘干处理；然后加入聚乙烯醇造粒，将造粒的粉体通过压片机预成型后再经30MPa～40MPa下压制成胚体，将所得的胚体在马弗炉中在600～800℃下排胶2～4h，然后于1500～1700℃下烧结1～5h，随炉冷却至室温得到陶瓷。本发明原料资源丰富，制备工艺简单，生产成本较低，所获得的一种高韧性、高硬度耐磨陶瓷具有优良的耐磨性，同时还具有较高的硬度和韧性。
