Preparation method of high-toughness wear-resistant WC composite material
The invention discloses a preparation method of a high-toughness wear-resistant WC composite material, and relates to a preparation method of a ceramic material. The high-toughness wear-resistant WC composite material is prepared from the following components in percentage by mass: 0.1 to 2 percent of GNPs-SiCw composite powder raw material and the balance of WC powder. The main process comprises the following steps: adding GNPs-SiCw composite powder raw materials into a liquid medium, carrying out ultrasonic stirring, and then adding WC powder to obtain a mixed solution; the mixed solution is subjected to ball milling, drying and screening, and ceramic composite powder is obtained; and sintering the ceramic composite powder to obtain the high-toughness wear-resistant WC composite material. According to the invention, the problem of bonding between different reinforced phases and the problem of difficult dispersion of the added whiskers are well solved, the use of strategic scarce resource Co is reduced, the mechanical properties and wear resistance of the WC composite material are effectively improved, and the application range of the material in the industrial field is expanded.
一种高强韧耐磨WC复合材料的制备方法，涉及一种陶瓷材料的制备方法。高强韧耐磨WC复合材料按质量分数为0.1～2％的GNPs‑SiCw复合粉体原料和余量的WC粉体制备而成。主要工艺：将GNPs‑SiCw复合粉体原料加入液体介质中进行超声搅拌，随后加入WC粉体后得到混合溶液；将混合溶液进行球磨，干燥和筛分，得到陶瓷复合粉体；陶瓷复合粉体烧结，得到高强韧耐磨WC复合材料。本发明很好解决了不同增强相间的结合性问题以及外加晶须的难分散问题，减少了战略性稀缺资源Co的使用，有效提高了WC复合材料力学性能及耐磨性，扩大了材料在工业领域的应用范围。
