Hard alloy material, manufacturing method, tool and wear-resistant member |
| abstract |
PROBLEM TO BE SOLVED: To provide a tungsten carbide hard alloy material, a method for producing the hard alloy material, a tool including the hard alloy material, and a wear-resistant member. A hard alloy material of the present invention includes a hard phase mainly composed of tungsten carbide and a binder phase unevenly distributed in contact with the hard phase and mainly composed of copper. The hard alloy material may have a Vickers hardness of 1000 to 2000 Hv5. The hard alloy material of the present invention is obtained by mixing powder of tungsten carbide particles and powder of copper particles (S103) and sintering under pressure (S105). At this time, tungsten carbide particles having an average particle size of 100 nm to 300 nm can be used. [Selection] Figure 2 |
