摘要： The invention relates to a production method of the powders composed of spherical heavy metal particles utilizing an ultrasonic atomization, where these powders can be applied in industrial applications, like additive manufacturing and several other. The method for production of heavy metal powders by ultrasonic atomization comprises providing a heavy metal raw material (5) in the vicinity of a heat source (13) being an electric arc (13), heating the heavy raw material (5) by the electric arc (13), so as to create a molten metal pool (21) on a sonotrode (3), the molten metal pool (21) having a temperature equal to or greater than the melting temperature of the heavy metal raw material (5), but below the vaporization temperature of the heavy metal raw material (5), providing ultrasonic mechanic vibrations by the sonotrode (3) to the molten metal pool (21), so as to cause the heavy metals droplets (11) being ejected from the molten metal pool (21), directing the ejected heavy metal droplets (11) away from the molten metal pool (21), so as the heavy metal droplets (11) freely cool down within a predetermined distance at least by radiation and transform to a heavy metal powder (11), collecting the heavy metal powder (11), so as to collect at least 75% of the heavy metal raw material (5) in the form of the heavy metal powder (11′).

摘要： The present disclosure generally relates to a method of fabricating a graded metallic structure by additive manufacturing and the graded metallic structure thereof. The method comprises preparing a material powder in a supply container, the material powder is partitioned into a plurality of longitudinal volumes and comprises different metallic powders, performing an additive manufacturing process comprising supplying layers of the material powder from the supply container, displacing the layers of material powder to a fabrication platform and fusing the layers of material powder on the fabrication platform to form the graded metallic structure, wherein at least one longitudinal volume has a varying transverse cross-sectional area and at least one longitudinal volume has a varying longitudinal cross-sectional area, such that the fused metallic powders in the graded metallic structure are graded along the longitudinal and the transverse. This method is proven to be effective to make graded metal parts with composition gradients in two dimensions.
