Abstract

The invention discloses a high-performance hard alloy material, and belongs to the field of hard alloy materials. The high-performance hard alloy material is prepared by the following raw materials inparts by weight: 65-80 parts of WC, 5-10 parts of Co, 10-15 parts of TiC, 3-8 parts of Ni, and 0.2-0.7 part of grain growth inhibiting agent; preferentially, the high-performance hard alloy materialis prepared by the following raw materials in parts by weight: 70-75 parts of WC, 7-9 parts of Co, 12-14 parts of TiC, 4-6 parts of Ni, and 0.3-0.5 part of grain growth inhibiting agent; the grain growth inhibiting agent is TaC; and the weights of all the components have the following relations: Ni/(Co+Ni) is not more than 0.4 and not less than 0.3; and (0.06WC+0.2TiC)/(WC+Co+TiC+Ni) is not more than 0.08 and not less than 0.05. Through improvement of the formula, the high-performance hard alloy material reduces adding of such expensive materials as Co and TaC, so that the production cost is reduced; and through reasonable batching, the hardness, the toughness and the cutting performance of the finally prepared high-performance hard alloy material are greatly improved compared with a traditional hard alloy material.

Description

technical field [0001] The invention relates to the field of cemented carbide materials, and more particularly to a high-performance cemented carbide material. Background technique [0002] With the rapid development of industrial technology, cemented carbide tool materials have rapidly penetrated into all aspects of industrial production, gradually replacing the original high-speed steel materials, and showing unparalleled excellent performance. In order to cater to the paper processing tool, the traditional slitting tool material is changed from high-speed steel material to cemented carbide material. [0003] The main component of cemented carbide is tungsten carbide (WC). Generally, cobalt is used as the bonding phase. It is produced by powder metallurgy and has high wear resistance and strength. Its high wear resistance increases its service life by 10-30 times, greatly improves production efficiency, reduces waste, and reduces production costs, and has been recognized ...
