  • Patent number: 11117190
    Abstract: A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.

  • Patent number: 8845956
    Abstract: The disclosure relates to a method for production of a component, such as a contact piece, for a switchgear assembly. To introduce a slot and apply a contact outer contour directly during the powder-metallurgical production process of the contact material, contouring in the form of a slot or slots is introduced into the powder-metal material, which is located in a mold, essentially in a direction parallel to a normal to a surface of the component, to form the component with a slot.

  • Patent number: 8840007
    Abstract: The invention relates to a compound sealing method for glass plates, which is characterized by realizing the air-tight joint between compounded glass plates in a preset position by using a metal brazing technology. The invention provides a brand new technological method for the compound sealing between glass plates. The method has the advantages of firm connection in sealing positions, high air tightness, favorable thermal shock resistance and the like, and the annealing of toughened glass are avoided because of a lower brazing temperature used, thereby providing convenience to the processing of toughened vacuum glass, toughened insulated glass and other toughened compound glass products.

  • Publication number: 20140234650
    Abstract: According to the invention, there are disclosed a power metallurgy composite cam sheet and a fabrication method thereof. The power metallurgy composite cam sheet is constructed by combining a power metallurgy cam be composited on a surface of a matrix. The fabrication method of the power metallurgy composite cam sheet includes sinter welding, braze welding, argon arc welding, laser welding, hot pressing and other methods. The powder metallurgy composite cam sheet fabricated by the invention has merits of stable size, good impact toughness, good abrasion resistance, low cost and so on, so that it can replace an integral cam sheet that is currently fabricated by forging, drawing, power metallurgy or other process. It is suitable for the case where a hollow camshaft is prepared by mechanical assembly, hydraulic forming, welding or other process, so that the usage requirements of an assembled camshaft can be met.

  • Patent number: 8800848
    Abstract: Methods for forming a wear resistant layer metallurgically bonded to at least a portion of a surface of a metallic substrate may generally comprise positioning hard particles adjacent the surface of the metallic substrate, and infiltrating the hard particles with a metallic binder material to form a wear resistant layer metallurgically bonded to the surface. In certain embodiments of the method, the infiltration temperature may be 50° C. to 100° C. greater than a liquidus temperature of the metallic binder material. The wear resistant layer may be formed on, for example, an exterior surface and/or an interior surface of the metallic substrate. Related wear resistant layers and articles of manufacture are also described.

  • Publication number: 20140193286
    Abstract: In a method for the production of a treatment element for a screw machine, a treatment element core of a first metal material is arranged in an inner space of a capsule of a hot isostatic pressing installation so that a contoured annular space is formed between a capsule wall and a treatment element core. The annular space is filled with a powder of a second metal material so as to produce an anti-wear layer. Afterwards, the treatment element blank is produced in such a way that the materials are combined by hot isostatic pressing to form a composite body. The treatment element blank is then post-processed to form the treatment element. The method according to the invention simplifies the production of treatment elements by in particular simplifying post machining and/or heat treatment of the anti-wear layer thus produced.
