Ternary boride composite ceramic, preparation method thereof and application of ternary boride composite ceramic as composite ceramic wire-drawing die
The invention belongs to the technical field of composite ceramics, and particularly relates to a ternary boride composite ceramic, a preparation method thereof and application of the ternary boride composite ceramic as a composite ceramic wire-drawing die. Tungsten boride, boron carbide and cobalt boride are used as main raw materials, meanwhile, a small amount of grain inhibitor, rare earth oxide, solid lubricant and silicon nitride whisker are added, the ternary boride composite ceramic mold is prepared, the process is simple, and the cost is low. A traditional carbide raw material is replaced by boride, and a proper amount of solid lubricant is added, so that the material has excellent wear resistance and friction resistance. The grain inhibitor and the rare earth oxide have the effects of refining grains and enhancing the toughness of the material, and the silicon nitride whisker can enhance the toughness of the material. Therefore, compared with a hard alloy wire-drawing die, the ternary boride composite ceramic wire-drawing die prepared by the invention has better high-temperature oxidation resistance and antifriction performance, and has better toughness compared with a polycrystalline diamond wire-drawing die, and the service life of the die can be remarkably prolonged.
本发明属于复合陶瓷技术领域，具体涉及一种三元硼化物复合陶瓷及其制备方法和作为复合陶瓷拉丝模具的应用。本发明以硼化钨、碳化硼、硼化钴为主体原料，同时添加了少量的晶粒抑制剂、稀土氧化物、固体润滑剂和氮化硅晶须，制得三元硼化物复合陶瓷模具，工艺简单和成本低。本发明以硼化物代替传统碳化物原材料，并添加适量的固体润滑剂，使材料兼具优异的耐磨性与减摩性。晶粒抑制剂和稀土氧化物有细化晶粒、增强材料韧性的作用，氮化硅晶须可以增加材料强韧性。因此，本发明制备的三元硼化物复合陶瓷拉丝模具，相比于硬质合金拉丝模具有更好的抗高温氧化性能及减摩性能，比聚晶金刚石拉丝模具有更好的韧性，可以显著提升模具使用寿命。
