    Abstract: A method of producing a Metal Matrix Composite (MMC) with uniform surface layers is disclosed. First, a low volume fraction compressible discontinuous ceramic fiber paper is set on the base of a mold cavity. Next, an array of reinforcement preform(s) (1×1,2×2, 4×4, 2×8, etc) are set in the mold on top of the ceramic fiber paper. A top layer of ceramic fiber paper is next placed on the array of reinforcement preforms and the mold cover seals the mold. The reinforcement porous preform(s) are held to the center of the mold cavity when the sealed mold compresses the top and bottom layers of ceramic fiber paper. The ceramic fiber paper exerts an equal and opposite force on the reinforcement preform(s) within the closed mold centering the preform(s) within the mold cavity. The mold cavity is next infiltrated under pressure with molten metal allowing for metal to penetrate into any open porosity of the ceramic fiber paper, reinforcement preform(s), and areas within the mold cavity that contain open spaces.

  • Patent number: 7341093
    Abstract: Described are wrought forms of copper alloys for infiltrating powder metal parts, the method for preparing the copper alloys and their wrought forms, the method for their infiltration into a powder metal part, and the infiltrated metal part infiltrated with the novel alloys having a generally uniform distribution of copper throughout and exhibiting high transverse rupture strength, tensile strength and yield strength. Infiltrated metal parts prepared by infiltrating powder metal parts with reduced amounts of the novel infiltrant typically weigh less and have superior strengths compared to similarly prepared infiltrated metal parts prepared with standard methods and conventional infiltration.

  • Patent number: 7296610
    Abstract: A method of manufacturing metallic components consisting of at least two different materials, one of them being an iron-based alloy and the other an aluminum-based alloy, and involving the steps of: depositing a metallic layer onto the body made from the iron-based alloy, said layer being an aluminum-based alloy, preferably based on Al—Si or Fe, placing the coated body in a casting mold and casting an aluminum-based alloy about the coated body. Prior to placing the body in the casting mold, the metallic layer of the body is sprayed and/or blasted with silicon powder and/or Borax (Na2B4O7—10H2O, hydrated sodium borate).

  • Patent number: 7284590
    Abstract: A method for manufacturing cast components, in which method the cast mold and/or macroscopic inserts to be placed either totally or partly inside thereof are left totally or partly as a part of the final component to be used, after the casting the piece is further treated with temperature and/or pressure in order to improve the compactness of both the cast materials and the materials acting as inserts and to improve the bond between the cast material and the solid material attached thereto, and the portion of the solid or partly solid material (inserts) to be placed into the cast mold and remaining in the final component, inclusive the portion of the mold eventually remaining in the final component, of the weight of the total component is more than 3 percent by weight.

  • Patent number: 7100671
    Abstract: In a method of manufacturing a cylinder head having a partition plate for an intake port, there is prepared a partition plate having an intake-side distal end and a cylinder-side distal end. The partition plate is located in a core to form the intake port and molten metal is supplied to a periphery of the partition plate. After solidifying the molten metal, the core is removed. At least the intake-side distal end of the partition plate is located in an expansion-permit space that permits thermal expansion of the partition plate caused by heat of molten metal.

  • Patent number: 7051783
    Abstract: The invention relates to a method for forming a green article for subsequent sintering or infiltration. This method includes providing a mold having an internal cavity that outlines the shape of the article, introducing metal or ceramic particles into the mold in an amount sufficient to provide the article in a desired size, adding a solution comprising an organic fluxing agent onto the particles with the solution carrying the organic fluxing agent into interstices between the particles, and freezing the solution to form a solid green article. The invention also relates to an apparatus and method for manufacturing dimensionally stable articles.

  • Patent number: 6886622
    Abstract: A damped blade is provided that includes a blade structural member defining at least one coolant channel and a liner formed of a shape memory alloy extending at least partially along the at least one coolant channel defined by the blade structural member. The shape memory alloy that forms the liner is maintained generally at its transition temperature by means of coolant circulated through the coolant channel. The shape memory alloy that forms the liner will resist the onset of vibrations within the blade, thereby effectively damping blade vibrations. A method of fabricating a damped blade is also provided.

  • Patent number: 6865807
    Abstract: A cylinder block production method is characterized by having, as a step prior to a cast-enclosing step of cast-enclosing a cast iron-made cylinder liner within a cylinder block body, an erosion-wash step of washing an outer peripheral wall surface of the cylinder liner and eroding a portion of a base structure of the cast iron forming the outer peripheral wall surface of the cylinder liner so as to form many small protrusions on the outer peripheral wall surface by jetting a high-pressure fluid onto the outer peripheral wall surface of the cylinder liner, in order to improve strength of adhesion between the cylinder liner and the cylinder block body. Since the base structure is partially eroded, complicated-shape small protrusions can be formed. Furthermore, sand and a mold release agent adhering to the outer peripheral wall surface of the cylinder liner can be removed. Therefore, the adhesion strength will improve.
