PREP

The Plasma Rotating Electrode Process operates on the following technical principle: under the protection of a high-purity inert atmosphere, the plasma induces an electric arc at the end of a high-speed rotating electrode rod, causing it to melt; the centrifugal force generated by the high-speed rotation of the electrode rod then ejects the molten metal, atomizing it into fine droplets; these atomized molten metal droplets subsequently condense into spherical powders within the inert atmosphere environment.

Characteristics of PREP Powder Production

1、

Uniform PSD

The powder features a narrow and concentrated particle size distribution and high sphericity. Alloy powders produced by gas atomization mainly have particle sizes ranging from 0 to 150 μm. Alloy powders fabricated via plasma rotating electrode process (PREP) show particle sizes predominantly in the range of 20–200 μm.

2、

High sphericity

Sphericity exceeds 95%, and the powder is nearly free of hollow particles and satellite particles.

3、

High purity

Free of metallic and non-metallic impurities, low oxygen content.

Advantages of PREP in Additive Manufacturing

1、No defects such as air gaps, entrapped pores, precipitated pores and cracks induced by hollow spheres are generated during printing.

2、The powder has fine particle size and narrow particle size distribution. Little or no spheroidization and agglomeration occur during printing, delivering superior surface finish and fully guaranteed printing consistency and uniformity.

3、The powder exhibits high sphericity, good flowability and high apparent density, and the printed parts achieve higher relative density.

4、The powder features good flowability and uniform powder spreading.

5、The powder has low oxygen content, low surface activity and good wettability, with little or no spheroidization and favorable melting behavior.
