Purpose
1.A large number of high-speed cutting tools, kiln structure materials, jet engine parts, metal ceramic materials, resistance heating elements, etc.
2.Used for manufacturing cutting tools, wear-resisting parts, smelting crucible of copper, cobalt, bismuth and other metals, wear-resisting semiconductor film.
2.Used for manufacturing cutting tools, wear-resisting parts, smelting crucible of copper, cobalt, bismuth and other metals, wear-resisting semiconductor film.
3.Used as super hard cutting tool material, wear resistant material. It can form solid solutions with many carbides. Wc-tic-co carbide tool has been widely used. It can also be used as a modified additive of NBC-C and TAC-C ternary system carbide, which can not only reduce sintering temperature, but also maintain good properties, and can be used as space materials.
Particle size
WC (tungsten carbide) of different particle size is used in different uses of cemented carbide. Carbide cutting tools: such as foot cutting machine blade, V-cut tool and other finishing alloys using ultra-fine, sub-fine and fine particle WC, coarse alloy using medium particle WC, gravity cutting and heavy cutting alloy using medium and coarse particle WC as raw materials; Mining tools: rock hardness is high, impact load is large, coarse particle WC is used, small impact load of rock is small, medium particle WC is used as raw material; Wear-resistant parts: When emphasizing their wear resistance, compression resistance and surface finish, ultra-fine, sub-fine, fine and medium particle WC are used as raw materials, and medium and coarse particle WC are mainly used as raw materials for impact resistant tools.
The theoretical carbon content of WC is 6.128% (atomic 50%). When the carbon content of WC is greater than the theoretical carbon content, free carbon (WC+C) appears in WC. The presence of free carbon makes WC grains around it grow up during sintering, resulting in uneven grains of cemented carbide. Tungsten carbide generally requires high combined carbon (≥6.07%), free carbon (≤0.05%), the total carbon is determined by the production process and use range of cemented carbide.
Under normal circumstances, the total WC carbon used in paraffin vacuum sintering is mainly determined by the chemical and oxygen content in the pressure block before sintering. Containing one oxygen will add 0.75 carbon, that is, WC total carbon =6.13%+ oxygen %×0.75 (assuming that there is a neutral atmosphere in the sintering furnace, in fact, most vacuum furnaces are carburizing atmosphere, the WC total carbon used is less than the calculated value).
At present, the total carbon content of WC in China can be roughly divided into three types: the total carbon content of WC used in paraffin vacuum sintering process is about 6.18±0.03% (the free carbon will increase). The total carbon content of WC for hydrogen sintering in paraffin process is 6.13±0.03%. Total WC carbon for hydrogen sintering in rubber process =5.90±0.03%. The above processes are sometimes crossed, so the determination of WC total carbon depends on the specific situation.
The WC total carbon used in the alloy with different application range, different Co (cobalt) content and different grain size can be adjusted slightly. Tungsten carbide with high total carbon can be used in low cobalt alloy, while tungsten carbide with low total carbon can be used in high cobalt alloy. In short, the specific use of cemented carbide needs different requirements for tungsten carbide particle size is also different.
