Various powder metallurgy technology

In the process of powder metallurgy, the preparation of powder is bound to be involved. In this trend, how should metal powder injection molding manufacturers choose powder metallurgy technology? The following is a brief introduction of the "diversified" powder metallurgy powder technology categories and the process of powder production.

The process of powder metallurgy can be divided into three categories

1、Rapid solidification atomizing powder making technology；

2、Mechanical alloy powder technology；

3、Preparation technology of ultramicro powder.

The rapid solidification and atomizing powder making technology of powder metallurgy is relatively direct, that is, the liquid metal or alloy is smashed and quickly condensed to obtain the powder material. This kind of powder making technology can effectively reduce the segregation of alloy components, so the obtained powder components are more uniform.

Due to different atomizing media used, the atomization methods used in powder metallurgy are also diversified, such as secondary atomization, gas atomization, high-pressure water atomization, centrifugal atomization and vacuum atomization. In the second stream atomization, when the atomizing medium and the metal liquid flow through the nozzle spout, the two streams of liquid impact each other, thus breaking the liquid flow, and then spray powder. In the gas atomization process, the gas pressure usually reaches 2 ~ 8 MPa. Due to the use of high-density water as the atomizing medium, the condensation rate achieved by the high-pressure water atomization method is higher than that of the general gas atomization method, so the powder is usually irregular in shape.

Mechanical alloying is the process of making alloy powder or composite powder from elemental powder, which is done in high energy ball mill. It needs to be ground between powder particles, powder particles and grinding ball for a long time before the powder can be broken and torn.

In powder metallurgy, ultramicro powder preparation technology has obvious different physical, chemical and mechanical properties due to small particle size.
