Description:
In the process of ultrasonic atomization of metal powder the raw material is fed into the pressurized atomization chamber where an electric arc is created to melt the material. Ultrasonic vibrations are transmitted through a sonotrode to the molten metal bath, forming capillary waves that eject metal droplets with a diameter that depends on the ultrasonic frequency, surface tension and density of the liquid metal. The droplets are ejected into a cooled stream of argon gas and rounded by surface tension into near-perfect spheres. The droplets then cool and solidify before being sorted and collected.
This atomizer is capable of producing a wide range of reactive and non-reactive metal powders, including aluminum, copper, stainless steel, titanium and other alloys.
