[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C. Cemented carbide is widely used as a tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used to cut difficult-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc. The production process of cemented carbide includes two steps: compaction and sintering. Before the compacted cemented carbide is sintered (the compacted cemented carbide is a round cake-shaped structure), the staff needs to apply a layer of liquid graphite on the outer surface of the cemented carbide to improve the high temperature resistance of the cemented carbide (graphite is a high temperature resistant material and is not easy to react physically and chemically with cemented carbide products).
