Powder metallurgy is an effective method for preparing cemented carbide. Its main features include:
Powder metallurgy can be used to prepare cemented carbide with fine grains and uniform structure, thereby improving the mechanical properties of the material.
By adding alloying elements and using different sintering processes, cemented carbide with various excellent properties can be obtained.
Powder metallurgy can produce carbide with complex shapes and structures, such as solid carbide cutting tools.
The powder metallurgy method can realize the composite of cemented carbide and other materials to obtain better mechanical properties and application range.
Compared with the smelting method, the powder metallurgy method can reduce energy consumption and environmental pollution.
However, there are also some difficulties in the powder metallurgy method. For example, parameters such as the composition, particle size, and sintering temperature of the powder need to be controlled during the manufacturing process to ensure the performance and quality of the final product. In addition, the production cost of powder metallurgy is also high, and the cost and quality of the production process need to be strictly controlled.
