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： A thermal spray material feedstock is provided for “flash-carbide” coatings. Flash carbide coatings are thin, dense, and smooth thermal spray coatings that self-activate the substrate. Flash-carbide coatings form and peen the coating to impart compressive stress for good adhesion and corrosion resistance. To achieve this combination of properties and performance, a powder that includes fine, dense, and angular particles is used; however, this powder alone results in a poor deposition efficiency of typically less than 20%. The present disclosure mitigates the poor deposition efficiency of this powder alone by providing a composition having two or more different particles at a specific ratio to improve deposition efficiency with sufficient optimized stress and corrosion properties and, in some cases, an increase in coating performance.

摘要： A soft magnetic alloy powder comprises first particles to fifth particles, each having a particle size within a specific range. Among the first particles to the fifth particles, nth particles have an average particle size xn (μm), an average circularity yn, and a variance zn of circularity, where nth is any ordinal number from first to fifth. Points (xn, yn) (n=1 to 5) plotted in an xy plane define an approximate straight line having a slope “my” of −0.0030 or more. Points (xn, zn) (n=1 to 5) plotted in an xz plane define an approximate straight line having a slope “mz” of 0.00050 or less.
