Abstract Scope |
Current methods for the production of spherical powders restrict the development of custom particles with tailored chemical compositions. This challenge is even greater when the input material is already a powder. The proposed Powder2Powder ultrasonic atomization process based on plasma melting allows to change the particle size, morphology and form an alloy in-situ. During processing the liquid, in contact with a surface vibrating at ultrasonic frequencies, forms standing capillary waves that lead to the ejection of fine droplets. As the amplitude of these waves increases, the wave crests can reach a critical height where the cohesive forces of the liquid are overcome by the surface tension.
The material in the form of powder was used to prepare custom alloy from the powder blend which was melted in the plasma stream and atomized from the sonotrode. Additional case studies will be presented using other out-of-spec additive manufacturing feedstocks. |
