Abstract: A nickel powder with an average particle size of 0.05 to 1.0 μm, which is composed of nickel particles having an oxidized surface layer and containing sulfur, wherein the sulfur content with respect to the total weight of the powder is 100 to 2000 ppm, and the intensity of a peak identified to sulfur bonded to nickel in surface analysis by ESCA of the nickel particles varies in a direction toward the center from the surface of the particles, and this intensity has its maximum at a location deeper than 3 nm from the particle outermost surface. This nickel powder is manufactured by bringing a nickel powder containing sulfur and dispersed in a non-oxidizing gas atmosphere into contact with an oxidizing gas at a high temperature.

Abstract: An additive manufacturing powder particle including a surface and at least one functional group formed on the surface, wherein the at least one functional group increases laser energy absorption of the additive manufacturing powder particle. The additive manufacturing particle is treated with plasma radiation to form hydroxyl functional groups on a surface of the additive manufacturing powder particle, where the hydroxyl functional groups have a molecular vibrational frequency corresponding to a laser wavenumber range of laser energy of an additive manufacturing process, and where the plasma radiation treating the additive manufacturing powder particles depends on the laser energy of the additive manufacturing process. Treating the additive manufacturing powder particle with the plasma radiation increases laser energy absorption of the additive manufacturing powder particle when the additive manufacturing particle is exposed to the laser energy, produced by a carbon dioxide laser, of the additive manufacturing process.

Abstract: The present invention provides a production method of copper-carbon nanofibers, which can realize oxidation-resistant characteristics and process simplification, the production method comprising the steps of: forming a metal precursor-organic nanofiber comprising a metal precursor and an organic substance; and forming a metal-carbon nanofiber by performing a selective oxidation heat treatment to the metal precursor-organic nanofiber so as to simultaneously oxidize carbon of the organic substance and reduce the metal precursor to a metal, wherein the metal has a lower oxidation resistance than the carbon; the selective oxidation heat treatment is performed through a singly heat treatment step, not a plurality of heat treatment steps; and metal-carbon nanofibers with different structures may be formed according to the amount of partial oxygen pressure under which the selective oxidation heat treatment is performed.
