Carbide Gear Cutter Base Material
When manufacturing cemented carbide, the particle size of the selected raw material powder is between 1 and 2 microns, and the purity is very high. The raw materials are batched according to the prescribed composition ratio, and alcohol or other media are added to wet grinding in a wet ball mill to make them fully mixed and pulverized. Sieve the mixture. Then, the mixture is granulated, pressed, and heated to a temperature close to the melting point of the binder metal (1300-1500 °C), the hardened phase and the binder metal will form an eutectic alloy. After cooling, the hardened phases are distributed in the grid composed of the bonding metal and are closely connected with each other to form a solid whole. The hardness of cemented carbide depends on the hardened phase content and grain size, that is, the higher the hardened phase content and the finer the grains, the greater the hardness. The toughness of cemented carbide is determined by the binder metal. The higher the binder metal content, the greater the flexural strength.
Little knowledge of cemented carbide
Density: The mass per unit volume, generally decreases with the increase in the proportion of the binder phase
Hardness: The ability of a material to resist elastic deformation, plastic deformation, or failure. Generally, it decreases with the increase of the bonding phase ratio.
Flexural strength: the ability of a material to resist bending without breaking.
Fracture Toughness: The ability of a material to resist the unstable growth of cracks.
