Abstract：This article introduces the basic principles and powder characteristics of the plasma rotating electrode atomization
technology (PREP) preparation of spherical metal powders. The classification, characteristics and equipment
status of the existing plasma rotating electrocle atomization technology are reviewed. Based on the introduction
of the crushing mechanism of the existing PREP technology and the powder morphology control strategy, the
importance of powder particle size prediction and the particle size prediction model of the existing PREP powder
are analyzed. The shortcomings of the existing model are analyzed, and the development direction of the PREP
technology research is prospected.
