Preparation method of metal ceramic cutter material
The invention provides a preparation method of a metal ceramic cutter material, which comprises the following steps: mixing Mo2C with the average particle size of 1-2 mu m, a quinary solid solution (W, Ta, Ti) CN with the average particle size of 2-3 mu m, Co with the average particle size of 1 mu m and Ni with the average particle size of 1 mu m in proportion according to a formula, taking hexane as a wet grinding medium, adding 400 milliliters into each kilogram of powder, controlling the ball-to-material ratio to be 4: 1, performing ball-milling for 72 hours, mixing with wax for 2 hours after ball-milling for 72 hours, and performing ball-milling to obtain the metal ceramic cutter material. The preparation method comprises the following steps: drying, granulating, pressing into a blade blank, and sintering for 1.5 hours at the temperature of 1450-1475 DEG C and under the low pressure of 4-6MPa to prepare the metal ceramic cutter material. Compared with the traditional TiC-based metal ceramic material, the metal ceramic cutter material prepared by the method provided by the invention has the advantages that the bending strength is obviously improved, and the service life is prolonged. Compared with a traditional TiC-based metal ceramic material, the metal ceramic material has obviously superior mechanical performance.
本发明提供的一种金属陶瓷刀具材料的制备方法，其制备方法为：按照配方，将平均粒径分别为1‑2μm的Mo2C、2‑3μm的五元固溶体(W，Ta，Ti)CN、以及1μm的Co，Ni按比例混合，以己烷为湿磨介质，每公斤粉末加400毫升，球料比为4:1，球磨时间72h，球磨时间72h后，再参蜡混合2h，干燥制粒后压成刀片毛坯，在温度1450℃‑1475℃，4‑6MPa低压烧结1.5h制成金属陶瓷刀具材料，通过本发明提供的方法制成的金属陶瓷刀具材料与传统TiC基金属陶瓷材料相比，其抗弯强度得到了明显的提升，相比传统TiC基金属陶瓷材料具有明显优越的机械性能。
