Tungsten carbide material for high-reliability wedge bonding chopper and production method of tungsten carbide material
A tungsten carbide material for a high-reliability wedge welding chopper is composed of, by weight, 55%-74.5% of WC, 20%-35% of TiC, 2%-15% of Co, 2%-15% of Ni, 0.15%-1% of Cr2C3, 0.15%-1% of VC, 0.5%-10% of Mo and 0.5%-15% of K. K is at least one of tantalum carbide, hafnium carbide, niobium carbide, rhenium carbide, tantalum niobium carbide solid solution and tungsten titanium carbide solid solution. According to the production method, a variable-diameter inner hole near-net mold pressing technology is adopted; according to the production method, the bonding use range of the tungsten carbide material is further broken through, the bonding service life of the tungsten carbide material is greatly prolonged, meanwhile, integral forming of the stepped inner hole tungsten carbide wedge welding chopper is achieved, the chopper machining procedures are greatly reduced, and the production cost of the tungsten carbide wedge welding chopper is greatly reduced.
一种用于高可靠性楔焊劈刀的碳化钨材料，其成分以重量百分比计，由以下组分组成：WC 55‑74.5%、TiC 20‑35%、Co 2‑15%、Ni 2‑15%、Cr2C3 0.15‑1%、VC 0.15‑1%、Mo 0.5‑10%、K 0.5‑15%，所述K为钽的碳化物、铪的碳化物、铌的碳化物、铼的碳化物、碳化钽铌固溶体、碳化钨钛固溶体中的至少一种；其生产方法是采用变径内孔近净模压技术；该生产方法进一步突破了碳化钨材料的键合使用范围，大幅提升碳化钨材料的键合使用寿命，同时，实现了台阶式内孔碳化钨楔焊劈刀的一体成形，大大减少了劈刀加工工序，大幅降低碳化钨楔焊劈刀生产成本。
