20150132173 - Laser processing of a bed of powdered material with variable masking: An additive manufacturing apparatus (10) and process including selectively heating a processing plane of a bed of powdered material (14) that includes a powdered metal material (14′), and may also include a powdered flux material (14″). The heating may be accomplished by directing an energy beam, such as a laser... Agent:
20150132174 - Rare earth composite magnets with increased resistivity: Dielectric rare earth fluorides are blended with rare earth magnet powders to produce high-resistivity fluoride composite rare earth magnets.... Agent:
20150132175 - High-density molding device and high-density molding method for mixed powder: A mixed powder placed in a container cavity is transferred to the cavity of a first die. A first pressure is applied to the mixed powder in the first die to form an intermediate green compact. The first die and the intermediate green compact are heated to heat the intermediate... Agent:
20150132176 - Method for the production of a metal bearing layer on a cylinder barrel of a hydrostatic displacement machine: A method for the production of a metal bearing layer (L) on a cylinder barrel (3) of a hydrostatic displacement machine (1), in particular of an axial piston machine, in which the metal bearing layer (L) is produced from a sintering powder in a sintering process. In a first production... Agent:05/07/2015 > 5 patent applications in 5 patent subcategories.
20150125333 - Below surface laser processing of a fluidized bed: A system and process of additive manufacturing using a fluidized bed of powdered material (14) including powdered metal material (14′) and powdered flux material (14′)′ including heating the powdered material with an energy beam (20) delivered from a location below a top surface (25) of the powdered material. The powdered... Agent:
20150125334 - Materials and process using a three dimensional printer to fabricate sintered powder metal components: A process and materials are disclosed to enable the formation of metal powder-polymer/plastic preform articles by three dimensional printing a green state article, debinding the polymer/plastic from the metal powder, and sintering the article to a final shape.... Agent: American Hakko Products, Inc.
20150125335 - Additive manufacturing using a fluidized bed of powdered metal and powdered flux: An additive manufacturing apparatus and process for selectively heating a fluidized bed of powdered material (14), including powdered metal material (14′) and powdered flux material (14′)′ with an energy beam (20). The powdered material is held within a chamber (12) to repair or manufacture a component (22). The powdered bed... Agent:
20150125336 - Method for producing ndfeb system sintered magnet: A method for producing a NdFeB system sintered magnet. The method includes: a hydrogen pulverization process, in which coarse powder of a NdFeB system alloy is prepared by coarsely pulverizing a lump of NdFeB system alloy by making this lump occlude hydrogen; a fine pulverization process, in which fine powder... Agent:
20150125337 - Method for producing rare earth sintered magnet, and mold: wherein the slurry is injected into the cavity so that the slurry travels from one place of the top end in the cross section perpendicular to the sliding direction of one of the outer peripheral surface and the inner peripheral surface, to one place of the top end in the... Agent: Hitachi Metals, Ltd.04/30/2015 > 2 patent applications in 2 patent subcategories.
20150118095 - Method of manufacturing a ferrous alloy article using powder metallurgy processing: A method of manufacturing a ferrous alloy article is disclosed and includes the steps of melting a ferrous alloy composition into a liquid, atomizing and solidifying of the liquid into powder particles, outgassing to remove oxygen from the surface of the powder particles, and consolidating the powder particles into a... Agent: Crs Holdings Inc.
20150118096 - High-density molding device and high-density molding method for mixed powder: A first die is filled with a mixed powder that is a mixture of a basic metal powder and a low-melting-point lubricant powder.
