    Abstract: This invention relates to a new ceramic-metal composite body and a method for producing the same. Par­ticularly, a compliant layer composition is utilized for preventing the rupture of a ceramic article (1) and/­or the yielding or failure of a metal during the pouring, solidification and cooling of a molten metal which has been cast around the ceramic. A slurry compo­sition for the compliant layer (2) includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the ceramic article (1) and thereafter is heat-treated to form a compliant layer (2). Ceramic-metal composite bodies comprising low strength hollow articles and high expansion coefficient metals may be manufactured according to the method of this invention.

    Abstract: An aluminum metal matrix composite comprises an aluminum metal matrix embedding a second filler (2), such as a ceramic second filler, and is formed by contacting, for example, a molten aluminum metal (20) with a permeable mass of second filler (22) within a ceramic impervious mold (12) formed by growing a polycrystalline oxidation reaction product into a first filler. By hermetically sealing the second filler (22) within the mold (12) with a body of molten aluminum metal (20), the latter spontaneously infiltrates the mass of second filler (22) at moderate temperatures, e.g. about 900°C, without need of any other infiltration expedients. The molten mass containing the infiltrated ceramic filler is solidified to provide the metal matrix composite which may be recovered from the mold (12). Optionally, the solidification is carried out under bonding conditions including maintaining the solidi­fying material in direct contact with the ceramic mold, to provide the metal matrix composite joined to the mold, or a part thereof, as a structural component.
