    Abstract: A method of manufacturing a metal-graphite brush material for a motor, which allows high-density formation of copper particles on the surfaces of graphite particles. The method: attaches copper complex to graphite particles; heat-treats the graphite particles attached with the copper particles, thereby to pyrolyze the copper complex to form copper particles on the surfaces of the graphite particles; forms the graphite particles having the copper particles formed thereon, together with a resin, into a formed product; and reduction-sinters the formed product under a reducing atmosphere to pyrolyze the resin, thereby to form a sintered body and also to reduce copper oxide formed in surface layers of the copper particles during the heat-treating.

    Abstract: An efficient process for producing fine nickel powder, capable of metallizing the powder at low temperature to prevent its sintering, and fine nickel powder produced by the process, composed of particles having a flat shape, diameter of limited variations and uniform thickness, and suitable for internal electrodes for laminate ceramic capacitors of high electric capacity. The process comprises a step for forming a nickel compound coated with gelatin by adsorbing gelatin on preformed nickel compound particles with different size and shape (Step (A)), and another step for converting said nickel compound coated with gelatin into fine particles containing metallic nickel and nickel oxide by heating the nickel compound coated with gelatin produced in Step (A) in an inert gas atmosphere (Step (B)). It may include an additional step (Step (C)), subsequent to Step (B), for completely reducing nickel oxide in said fine particles by heating at temperature lower than that for Step (B) in a reducing gas atmosphere.

    Abstract: The invention relates to the cost-effective manufacture of near-net shape titanium articles from sintered powders containing titanium and all required alloying elements. The cost-effective initial powder composition for subsequent room temperature consolidation and sintering contains: (a) 10-50 wt. % of underseparated titanium powder with ≦500 μm in particle size manufactured from underseparated titanium sponge comprising up to 2 wt. % of chlorine and up to 2 wt. % of magnesium. The underseparated titanium powder costs significantly less than that for fully separated powder of completely reduced sponge; (b) 10-90 wt. % of hydrogenated titanium powder, whereby this powder is a mixture of two hydrogenated powders A and B containing different amount of hydrogen: powder A contains amount of hydrogen in the range of 0.2-1 wt. % and powder B contains amount of hydrogen in the range of 2-3.9 wt. %. The powder with high hydrogen content provides purification of underseparated titanium powder during heat treatment and sintering, while the powder with low hydrogen content provides sufficient strength of green compacts as well as perfect structure and quality of the final sintered article; (c) 0-90 wt. % of standard grade refined titanium powder, and/or 5-50 wt. % of alloying metal powders: master alloys or elemental powders. The method includes (a) mixing said underseparated titanium powder, the C.P. titanium powder, the hydrogenated titanium powders containing different amount of hydrogen, (b) compacting the obtained blend by room temperature consolidation such as die pressing, molding, direct powder rolling, cold isostatic pressing, and/or metal injection molding to density at least 60% of the theoretical density, (c) additional crushing titanium hydride powders into fine fragments during consolidation at the pressure of 400-960 MPa to provide forming a uniform network of fine pores promoting healing effects during sintering, chemical cleaning and refining titanium powders in the compacted articles by heating to 300-900° C. and holding for at least 30 minutes to provide a reaction of Cl, Mg, and oxygen, with hydrogen emitted due to decomposition of titanium hydride, (e) heating in vacuum for sintering in β-phase zone of titanium in the temperature range of 1000-1350° C. and holding for at least 30 minutes, and cooling. The new technology allows the purity and mechanical properties of sintered titanium alloys and the manufacture of near-net shape sintered titanium articles to be controlled by a cost-effective process.

    Abstract: The invention relates to a method for producing contact makers for vacuum switching chambers, which are used in low-voltage, medium-high voltage, and high-voltage engineering, during which the contact makers are provided with slots extending from the middle area of the contact to the edge. The invention also relates to the contact maker itself. In order to improve a method for producing contact makers in vacuum switching chambers as well as a contact maker of the type in question so that the production method is distinctly less complicated, and the contact maker is sufficient for the highest functional demands, the invention provides that the contact makers are produced in a powder metallurgical process in which they are provided with near final contours and near final dimensions. During this process, said slots are already made in the green compact and are fixed during a subsequent sintering.
