Conclusions
The particle shape of a powder produced by the atomization of a molten metal with water under high pressure, unlike that of a powder atomized with a compressed gas, is determined by the actual density of the energy carrier (the steam:water ratio) in the contact zone, and can vary within wide limits, from spherical to jagged. The actual density of an energy carrier consisting of water and steam is a function of the temperature of the melt and also of the pressure of the water and the geometry of the atomizing device.
