Diversification of powder metallurgy pulverizing technology
How much do you know about the diversification of powder metallurgy pulverizing technology? The preparation process of powder inevitably involves the process of powder metallurgy. The preparation process of powder can be divided into three categories: rapid solidification atomization technology, mechanical alloy powder preparation technology, and ultra-fine powder preparation technology. Zhongwei Precision Powder Metallurgy Manufacturer:
The rapid solidification atomization powder making technology of powder metallurgy is more direct, that is, the liquid metal or alloy rapidly coagulates after crushing to obtain powder materials. This pulverizing technology can effectively reduce the segregation of alloy components and make the composition of alloy powder more uniform.

Due to the use of different atomization media, many atomization methods are also used in powder metallurgy powder making technology, such as secondary atomization, gas atomization, high-pressure water atomization, centrifugal atomization, vacuum atomization, etc. In the secondary flow atomization, when the atomizing medium and the metal liquid flow are sprayed through the nozzle, the two liquid flows collide with each other, thus crushing the liquid flow, and then spraying the powder.
In the gas atomization method, the gas pressure usually reaches 2 × 8 MPa, on this basis, smooth powder particles can be used in powder metallurgy. Because the water atomization method uses thick water as the atomizing medium, and the condensation speed is higher than that of the general gas atomization method, the shape of the powder is generally irregular.
Mechanical alloying is a method of producing alloy powder or composite powder from elemental powder. It is completed on the high-energy ball mill, and it can be broken and crushed only after a long time of grinding between the powder particles and the grinding ball.
Don't forget that there is also a preparation process of ultra-fine powder in powder metallurgy. The powder prepared by this technology has obvious differences in physical, chemical and mechanical properties due to its small particle size.
