Powder metallurgy factory tells you that the powder metallurgy process will inevitably involve powder preparation. The powder preparation process can be mainly divided into three categories, one is the rapid solidification atomization powder technology, and the other is mechanical alloy powder. Another category is ultrafine powder preparation technology.

The rapid solidification atomization powder milling technology of powder metallurgy is relatively straightforward, which is to rapidly condense the liquid metal or alloy after crushing, thereby obtaining powdery material. Powder metallurgy factory tells you that this type of milling technology can effectively reduce the segregation of alloy components, so the obtained alloy powder has a relatively uniform composition.
Powder metallurgy factory tells you that due to the different atomization media used, the atomization methods used in powder metallurgy powder technology also have a variety of choices, such as two-stream atomization, gas atomization, high-pressure water atomization, centrifugal atomization, vacuum Atomization, etc. Powder metallurgy factory tells you that in two-stream atomization, when the atomizing medium and the metal liquid flow are sprayed through the nozzle, the two liquid flows collide with each other, thereby breaking the liquid flow and spraying powder.
In the gas atomization method, the gas pressure generally reaches 2-8 MPa, and the powder particles with smooth surface can be obtained on this basis for powder metallurgy. The water atomization method uses water with a higher density as the atomization medium, so the condensation rate achieved is an order of magnitude higher than that of the general gas atomization method, so the shape of the obtained powder is generally irregular.
Powder metallurgy factory tells you that mechanical alloying powder milling technology is a way to prepare alloy powder or composite powder from element powder. Grinding for a long time will break and tear the powder. Powder metallurgy factory tells you about the ultrafine powder preparation technology in powder metallurgy. Due to the small particle size, the powders prepared by this technology have significantly different physical, chemical and mechanical properties.
