  • Ceramic filter element
    Patent number: 6394281
    Abstract: A process for sealing a ceramic filter by infiltrating a metal into an end of the filter is disclosed. The process includes the steps of contacting the end of a porous ceramic filter with a molten metal, whereby the metal enters into the ceramic matrix to substantially fill the void space. The ceramic filter is cooled to form a filter having a ceramic-metal composite portion. The present invention also provides a filter having an infiltrated metal seal. Methods for joining infiltrated ends are also provided.
    Type: Grant

  • Method for making near net shape ceramic-metal composites
    Patent number: 5676907
    Abstract: A process for fabricating ceramic-metal composites having continuous ceramic and metallic phases. The process includes the steps of contacting a porous ceramic matrix material having the general shape of an article of manufacture with molten metal whereby capillary action pulls the metal into the open porosity of the ceramic matrix to substantially fill the open void space. The present invention also provides a ceramic-metal composite having continuous metal and ceramic phases.

  • Method for making ceramic-metal gradient composites
    Patent number: 5525374
    Abstract: A process for fabricating ceramic-metal composites having ceramic and metal phases wherein the ceramic to metal ratio changes within the ceramic. The process includes the steps of contacting a porous ceramic matrix material with a molten metal whereby capillary action pulls the metal into the ceramic matrix to substantially fill the void space. The ceramic matrix has a porosity gradient wherein the infiltrated composite has a varying ratio of ceramic to metal.

  • Engine components including ceramic-metal composites
    Patent number: 5503122
    Abstract: Ceramic-metal composites are used in the fabrication of components for engines, particularly internal combustion engines. The composites are formed by infiltrating a molten metal into a porous ceramic matrix and cooling the metal to form a composite. Numerous engine components can be fabricated using this technique including valves, valve seats, exhaust port liners, pistons and rocker arms.
