COMPARISON OF METAL POWDER PRODUCTION METHODS: VACUUM INDUCTION ATOMIZATION AND MECHANICAL POWDERING WITH SPINDLE (BALL MILL)

Abstract

This thesis analyzes two main methods for producing metal powders: vacuum induction atomization and spindle (ball mill) method. The metal powders obtained through the vacuum induction atomization method can have uniform particle size and high quality, and this method prevents the oxidation of the molten metal. In a vacuum environment, the particle size and shape become small and uniform, which helps in obtaining high-quality powder. However, this process is quite complex, requiring specialized equipment and energy consumption, which increases production costs. Additionally, this method is particularly effective for metals prone to oxidation, such as aluminum or magnesium.
