摘要:
In a process for producing a hearing aid, comprising a housing made out, at least partially, of a metallic or ceramic part using powder injection molding technique (PIM) within the housing (1) at least one additional element (3) made out of a polymeric material is arranged for placing functional parts (5, 7, 13) within or at the housing (1) to reduce complexity of PIM parts and/or to compensate any tolerances due to the PIM process.
摘要:
A process for forming a medical device such as a stent that is formed of a molybdenum and rhenium alloy. Including the steps of forming a rod or tube having a surface and an outer cross-sectional area, in a metal alloy that is at least 99 weight percent of a solid solution of molybdenum and rhenium, drawing down said outer cross-sectional area of said rod, annealing said rod at an annealing temperature in an oxygen reducing or inert environment, cooling said annealed rod at a rate of at least 100C per minute, drawing down said rod by the reducing mechanism after said rod has been annealed and, annealing said rod at least one additional time at a temperature that is lower than a previous annealing. Further steps may include: laser cutting, etching, crimping, pilgering, electroplating, polishing, cleaning, pickling, ion beam deposition or implantation, sputter coating, vacuum deposition.

摘要:
Disclosed is a putter golf club head made of a tungsten alloy, in which the tungsten alloy normally used as a weight insert to control the center of gravity of the golf club is applied to the head of the putter, thus increasing stability and accuracy of putting. Additionally, a method of manufacturing the putter head is provided, including mixing 60 to 90 wt% tungsten and 10 to 40 wt% nickel, with impurities of less than 1 wt%; drying the mixture at temperatures lower than 100°C; removing impurities using a screen; forging the mixture at 2 to 5 ton/ CM3; pre-sintering the forged product at 800 to 1000°C; re-sintering the pre-sintered product at 1400 to 15004; cutting the sintered product to flatten surfaces thereof; machining the sintered product by electric discharging using an electrode; grinding the sintered product using a diamond wheel; and polishing the sintered product using diamond powder.
摘要:
A method of fabricating a high density thin component which can be used in an electrochemical converter comprises tape casting a material to form a tape followed by hot pressing of the tape to provide additional densification of the material. A plurality of tapes may be laminated together prior to hot pressing to provide a thicker structure or a composite structure. The materials used to produce the component may include silicon carbide, SiC, high chromium alloys, chromium iron alloys, (Cr-5wt%Fe-1wt%Y2O3) and chromium magnesium alloys (Cr-5wt%Ni-1wt%MgO). The fabrication method produces a high density component, including the application in an electrochemical converter, having a thickness of less than about 0.03 inches.
