Abstract
The present invention relates to forming a metal matrix composite between at least two bodies having a similar or a different chemical composition, the metal matrix composite functioning as a bonding means which bond to or fixes the bodies together. Particularly, a metal matrix composite is produced by a spontaneous infiltration technique by providing a filler material or preform with an infiltration enhancer and/or an infiltration enhancer precursor and/or and infiltrating atmosphere, which are in communication with the filler material or preform at least at some point during the process. Molten matrix metal then spontaneously infiltrates the filler material or preform, whereby the metal matrix composite serves to bond together two or more bodies.
