This invention relates generally to a novel method of manufacturing a composite body and to novel products made thereby. More particularly, the invention relates to a method of producing a self-supporting body comprising one or more boron-containing compounds, e.g., a boride or a boride and carbide, by reactive infiltration of molten parent metal into a bed or mass containing boron carbide, and, optionally, one or more inert fillers and permitting residual or excess parent metal, to remain bonded to the formed self-supporting body. Excess metal is used to form a bond between the reactively infiltrated body and another body (e.g., a metal or a ceramic body).

A method of producing a self-supporting body comprising producing a first composite body by: selecting a parent metal; heating said parent metal in a substantially inert atmosphere to a temperature above its melting point to permit infiltration of molten parent metal into a mass comprising boron carbide and to permit reaction of molten parent metal with said boron carbide to form at least one boron-containing compound; continuing said infiltration reaction for a time sufficient to produce said first composite body comprising at least one parent metal boron-containing compound; providing a quantity of excess metal to at least a portion of at least one surface of said first composite body wherein said quantity is sufficient to permit bonding of said first composite body to a second body; and bonding said first composite body to said second body thereby forming a self-supporting body.
