Background
The hard alloy is a powder metallurgy product which is sintered in a vacuum furnace or a hydrogen reduction furnace by taking carbide WC of high-hardness refractory metal as a main component and cobalt as a binder.
When the hard alloy is manufactured, the selected raw material powder has the granularity of several microns and high purity. The raw materials are proportioned, added with alcohol or other medium, wet-milled in a wet ball mill, fully mixed and pulverized, dried, sieved, added with forming agent such as wax or glue, dried and sieved to obtain the mixture. Then, the mixture is pelletized and pressed, and when the mixture is heated to be close to the melting point (1300-1500 ℃) of the bonding metal, the bonding metal combines the hard phases together, and the compact alloy is formed after cooling. The hardness of cemented carbides depends on the hard phase content and grain size, i.e. the higher the hard phase content, the finer the grains, the greater the hardness. The toughness of the hard alloy is determined by the binder metal, and the higher the content of the binder metal is, the higher the bending strength is.
