Titanium carbonitride-based micro-nano composite ceramic cutter material and preparation method thereof
The invention belongs to the technical field of material science, and relates to a titanium carbonitride (Ti (C0.7, N0.3))-based micro-nano composite ceramic cutter material and a preparation method thereof. The WC-ZrO composite material comprises the following raw materials in percentage by weight: 10.0%-30.0% of WC, 25.0%-25.0% of 3Y-ZrO, 3.0%-5.0% of a sintering aid and the balance of Ti (0.7% of C and 0.3% of N), wherein the particles of the WC, the sintering aid and the Ti (C0.7, N0.3) are micron-sized, the particles of the 3Y-ZrO2 are nano-sized, and the sintering aid is Ni and Co; the 3Y-ZrO2 is uniformly dispersed through a silane coupling agent. The titanium carbonitride-based micro-nano composite ceramic cutter material provided by the invention not only has high fracture toughness, but also greatly reduces a metal binding phase, so that the titanium carbonitride-based micro-nano composite ceramic cutter material has high hardness, thereby greatly improving the cutting processing performance of a titanium carbonitride-based micro-nano composite ceramic cutter and prolonging the service life of the cutter.
本发明属于材料科学技术领域，涉及一种碳氮化钛(Ti(C0.7,N0.3))基微纳复合陶瓷刀具材料及其制备方法。按照重量百分数计，包括以下原料：WC 10.0～30.0％，3Y‑ZrO25.0～25.0％，助烧结剂3.0～5.0％，余量为Ti(C0.7,N0.3)；其中，WC、助烧结剂、Ti(C0.7,N0.3)的颗粒为微米级，3Y‑ZrO2的颗粒为纳米级，助烧结剂为Ni和Co；3Y‑ZrO2通过硅烷偶联剂分散均匀。本发明提供的碳氮化钛基微纳复合陶瓷刀具材料不仅具有高断裂韧度，而且大大降低了金属粘结相，使其具有高硬度，因此，大大提高了碳氮化钛基微纳复合陶瓷刀具的切削加工性能和刀具寿命。
