    Abstract: The present invention relates to the use of a gating means in combination with a spontaneous infiltration process to produce a metal matrix composite body. Particularly, a permeable mass of filler material or a preform (2) is spon­taneously infiltrated by molten matrix metal (5) to form a metal matrix composite body. A gating means (3) is provided which controls or limits the areal contact between molten matrix metal (5) and the filler material or preform (2). The use of a gating means (3) provides for control of the amount of matrix metal (5) which can contact the preform (2) or filler material which may result in less machining of a formed metal matrix composite body compared with a similar metal matrix composite body made without a gating means (3) and/or ameliorates the tendency of a formed metal matrix composite body to wrap due to the contact between the formed composite body and matrix metal carcass.

    Abstract: The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a per­meable mass of filler material or a preform (4) with molten matrix metal (2) 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 (4), at least at some point during the process, which permits molten matrix metal (2) to spontaneously infiltrate the filler material or preform (4). Moreover, prior to in­filtration, the filler material or preform (4) is placed into contact with at least a portion of a second material such that after infiltration of the filler material or pre­form (4), the infiltrated material is bonded to the second material, thereby forming a macrocomposite body.
