Ⅰ PREP atomization powder making process introduction:

PREP, i.e. plasma rotating electrode process, is an advanced atomization powder making method. It makes metal or alloy into consumable electrode, and melts the electrode end to form liquid film under the action of coaxial plasma arc heating source. Subsequently, the liquid film is thrown out at high speed to form droplets under the action of rotating centrifugal force. These molten droplets rub against the inert gas (such as argon or helium) in the atomization chamber and are further broken under the action of shear stress. Finally, the molten droplets are rapidly cooled and solidified into spherical powder under the action of surface tension.

During the entire preparation process, the powder making system realizes automatic control through automatic vacuum program block, automatic inert gas charging and discharging program block, electric spindle automatic rotation program block, melting current automatic calculation program block and automatic feeding program block, etc., to ensure the stability and efficiency of the preparation process.

Ⅱ PREP atomization powder making process characteristics

1. High powder purity:
Due to the use of consumable electrode, the introduction of external impurities is avoided, so that the prepared powder has a high purity.

2. Wide and controllable particle size distribution: By adjusting process parameters such as electrode speed, current size, etc., the powder particle size can be precisely controlled to obtain powder products with a wide particle size distribution.

3. Good powder morphology: The powder prepared by the PREP process is spherical, smooth, has good fluidity and bulk density, and is conducive to subsequent processing and application.

4. High production efficiency: The PREP process has high production efficiency and capacity, which can meet the needs of large-scale production.

2. Aerospace: In the field of aerospace, high-performance metal and alloy powders are important raw materials for manufacturing key components such as engines and turbine blades. The PREP process can prepare powder products that meet the performance requirements of these components, providing strong support for the development of the aerospace field.

3. Electronic information: In the field of electronic information, the powder materials prepared by the PREP process can be used to prepare key components of electronic components, sensors and other products. These components have the characteristics of high precision and high reliability, which is of great significance for improving the performance and quality of electronic products.
