  • Publication number: 20140369846
    Abstract: An impeller vane includes at least a first metallic core material and at least a first wear resistant material, wherein the hardness of the at least first wear resistant material exceeds the hardness of the at least first metallic core material. The impeller vane consists of a plurality of layers of the at least first metallic core material and the at least first wear resistant material, wherein the layers extend from a leading edge of the impeller vane to the trailing edge of the impeller vane and are arranged alternatingly throughout the cross section of the impeller vane. An impeller includes at least one of the above impeller vanes. The invention also relates to methods for manufacturing an impeller vane and an impeller having such.

  • Publication number: 20130224058
    Abstract: A method for manufacturing a component having at least one internal cavity includes the step of providing a core element of metallic material that includes at least one cavity having a first opening covered by a cover element with a first and second side. A form partially surrounds the core element and cover element. The form is filled with metallic filling material and heated in a heating chamber that is pressurized with gas for a predetermined time period at a predetermined temperature and a predetermined isostatic pressure, so that a metallurgical bond is achieved between the core element, cover element and metallic filling material. The core element is arranged such that, after filling the form with metallic filling material, the second side of the cover element is covered with metallic filling material so that the cavity during heating is pressurized to the predetermined isostatic pressure.
