Patent number: 5620804Abstract: The present invention relates to the formation of a metal matrix composite body by the spontaneous infiltration of a molten matrix metal into a three-dimensionally interconnected material. Moreover, the three-dimensionally interconnected material may contain filler material within at least a portion of its porosity. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material and/or a three-dimensionally interconnected material and/or a matrix metal at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the three-dimensionally interconnected material and any filler material contained within at least a portion of the porosity of the three-dimensionally interconnected material.Type: GrantFiled: June 7, 1993Date of Patent: April 15, 1997Assignee: Lanxide Technology Company, LPInventors: Christopher R. Kennedy, Michael K. Aghajanian, Alan S. Nagelberg

Patent number: 5618635Abstract: The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltation of the filler material or preform, the infiltrated material is bonded to the second material, thereby forming a macrocomposite body.Type: GrantFiled: March 27, 1995Date of Patent: April 8, 1997Assignee: Lanxide Technology Company, LPInventors: Marc S. Newkirk, Danny R. White, Christopher R. Kennedy, Alan S. Nagelberg, Michael K. Aghajanian, Robert J. Wiener

Patent number: 5526867Abstract: The present invention relates to the formation of a macrocomposite body for use as an electronic package or container. The macrocomposite body is formed by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body or a metal or metal containing body. Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltration of the filler material or preform by molten matrix metal, the infiltrated material is bonded to said second material, thereby forming a macrocomposite body. The macrocomposite body may then be coated by techniques according to the present invention to enhance its performance or bonding capabilities.Type: GrantFiled: June 6, 1995Date of Patent: June 18, 1996Assignee: Lanxide Technology Company, LPInventors: Steven D.

Patent number: 5287911Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and novel products produced by the method. Particularly, a permeable mass of filler material or a preform is provided which has included therein at least two different matrix metal powders. Moreover, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material or preform, at least at some point during the process, which permits molten matrix metal, upon contact with the filler material or preform, to spontaneously infiltrate the filler material or preform. The presence of powdered matrix metal in the preform or filler material reduces the relative volume fraction of filler material to matrix metal.Type: GrantFiled: May 14, 1992Date of Patent: February 22, 1994Assignee: Lanxide Technology Company, LPInventors: Michael K.
