Abstract

The invention discloses a hard alloy material with light weight and high strength. The hard alloy material is characterized by being prepared from the following components by weight percent: 4% to 5% of Co, 46% to 51% of TiC, 2.5% to 3% of TaC, 1% to 1.2% of NbC, 9% to 10% of MoC, 9% to 10% of Ni, 0.3% to 0.5% of Si3N4, 1.4% to 1.7% of ZrC2 and 19% to 22% of WC. The hard alloy material disclosed by the invention can be used for manufacturing a cutting tool for cutting metals and alloy materials, and is good in abrasion resistance and red hardness. Thus, the service life of the cutting tool is long.

Description

technical field [0001] The invention relates to a hard alloy material and a manufacturing method thereof, in particular to a TiC-based lightweight high-strength hard alloy material and a manufacturing method thereof. Background technique [0002] TiC-based cemented carbide has very high hardness, high wear resistance, small friction coefficient, high oxidation resistance, high heat resistance and good chemical stability. However, its resistance to plastic deformation, brittle damage resistance, thermal conductivity, etc. are poor, and its resistance to abrasive wear is also low. Therefore, its application is not as wide as that of WC-based cemented carbide. Although Ti(C,N)-based cemented carbide is used as tool material, it is suitable for high-speed cutting and dry cutting of cast iron, ordinary steel, and high-hardness steel, and its performance is better than that of general cemented carbide tools in some processing situations, but the tool The service life is still di...
