摘要： It is an electrode material that is used as an electrode contact of a vacuum interrupter and that contains one or more parts by weight of a heat-resistant element and one part by weight of Cr, the remainder being Cu and an unavoidable impurity. A part of Cr powder and the heat-resistant element powder are mixed together, and this mixed powder is sintered such that a peak corresponding to Cr element disappears in X-ray diffraction measurement. A solid solution powder obtained by pulverizing a sintered body of the heat-resistant element and Cr obtained by the sintering is mixed with the remaining Cr powder, and this mixed powder is shaped and then sintered. A sintered body obtained by this sintering is infiltrated with Cu.

摘要： Devices, systems, and methods are directed to the use of nanoparticles for improving fabrication of three-dimensional objects formed through layer-by-layer delivery of an ink onto a powder of metal particles in a powder bed. More specifically, the ink may include metal nanoparticles suspended in a non-oxidizing aqueous solution to facilitate maintaining the metal nanoparticles in a stable form, providing a shelf-life suitable for transportation and storage of the ink in large-scale commercial operations. The ink may be delivered onto the powder of the metal particles in the powder bed, where the nanoparticles may interact with the metal particles to improve strength of the three-dimensional objects being fabricated. Also, or instead, the nanoparticles may reduce the likelihood of defects associated with subsequent processing of the three-dimensional objects (e.g., slumping and shrinking and/or inadequate densification of the final part).

摘要： It is a method for manufacturing an electrode material containing Cu, Cr, a heat-resistant element, and a low melting metal. A Cr powder and a heat-resistant element powder are mixed together in a ratio such that the Cr is greater than the heat-resistant element by weight. The mixed powder of the heat-resistant element and the Cr powder is baked. A MoCr solid solution obtained by the baking and containing a solid solution of the heat-resistant element and the Cr is pulverized and then classified. The classified MoCr solid solution powder, a Cu powder, and a low-melting metal powder are mixed together, followed by sintering at a temperature that is 1010° C. or higher and is lower than 1038° C., thereby obtaining the electrode material.
