Abstract: A nickel powder with a mean particle size of 0.05 to 1.0 μm, the nickel powder comprising a thin oxidized layer of nickel on a surface thereof and having an oxygen content of 0.3 to 3.0 wt. % and a carbon content of 100 ppm or less per specific surface area of 1 m2/g of the powder, in a weight proportion of carbon to the nickel powder of unit weight. When the powder is used for a conductive paste for forming inner electrode layers of a multilayer electronic component, it enables the decrease in the residual carbon amount after a binder removal process, thereby making it possible to obtain a multilayer ceramic electronic component with excellent electric characteristics and high reliability in which electrode layers excelling in continuity are formed without decreasing the strength and electric characteristics of the electronic component or creating structural defects.

Abstract: A method includes additively manufacturing an article in an inert environment, removing the article from the inert environment and placing the article in a non-inert environment, allowing at least a portion the article to oxidize in the non-inert environment to form an oxidized layer on a surface of the article, and removing the oxidized layer (e.g., to smooth the surface of the article). The method can further include relieving stress in the article (e.g., via heating the article after additive manufacturing).

Abstract: A process for applying a low coefficient of friction coating to interacting parts of a mechanical device. The low coefficient coating is comprised of nanoparticles of a metal melting below about 400° C., preferably bismuth. Interacting parts of a mechanical device, prior to assembly of the mechanical device, are submerged in a dispersion of the nanoparticles, then heated to an effective temperature, then cooled, thereby resulting in a coating of the nanoparticles onto the interacting parts.

Abstract: A method for gas atomization of oxygen-reactive reactive metals and alloys wherein the atomized particles are exposed as they solidify and cool in a very short time to multiple gaseous reactive agents for the in-situ formation of a protective reaction film on the atomized particles. The present invention is especially useful for making highly pyrophoric reactive metal or alloy atomized powders, such as atomized magnesium and magnesium alloy powders. The gaseous reactive species (agents) are introduced into the atomization spray chamber at locations downstream of a gas atomizing nozzle as determined by the desired powder or particle temperature for the reactions and the desired thickness of the reaction film.
