Abstract

Abstract 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).

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 111 words
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 self-supporting body comprising at least one parent metal boron-containing compound; and providing excess metal on at least one surface of said self-­supporting body to permit bonding of said self-supporting body to a second body.
Claim 2
Independent Claim 111 words
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 self-supporting body comprising at least one parent metal boron-containing compound; and providing excess metal on at least one surface of said self-­supporting body to permit bonding of said self-supporting body to a second body.
Claim 3
Independent Claim 79 words
A method of producing a self-supporting macrocomposite body comprising: reactively infiltrating a mass comprising boron carbide with a parent metal, said reactive infiltration occurring in a substantially inert atmosphere to result a reaction of said boron carbide with said parent metal to form at least one boron-containing compound in a reactively infiltrated body; and providing an excess amount of parent metal such that parent metal, upon cooling, remains bonded to the reactively infiltrated body, thereby forming a macrocomposite body.
Claim 4
Independent Claim 79 words
A method of producing a self-supporting macrocomposite body comprising: reactively infiltrating a mass comprising boron carbide with a parent metal, said reactive infiltration occurring in a substantially inert atmosphere to result a reaction of said boron carbide with said parent metal to form at least one boron-containing compound in a reactively infiltrated body; and providing an excess amount of parent metal such that parent metal, upon cooling, remains bonded to the reactively infiltrated body, thereby forming a macrocomposite body.
Claim 5
Independent Claim 107 words
A method of producing a self-supporting macrocomposite body comprising: 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 a boron carbide material and to permit reaction of molten parent metal with said boron carbide material, thereby forming at least one boron-containing compound; continuing said infiltration reaction for a time sufficient to produce said self-supporting body comprising at least one parent metal boron-containing compound; and thereafter contacting and bonding at least a portion of said produced self-supporting body with another metal, thereby producing a macrocomposite body.
Claim 6
Independent Claim 107 words
A method of producing a self-supporting macrocomposite body comprising: 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 a boron carbide material and to permit reaction of molten parent metal with said boron carbide material, thereby forming at least one boron-containing compound; continuing said infiltration reaction for a time sufficient to produce said self-supporting body comprising at least one parent metal boron-containing compound; and thereafter contacting and bonding at least a portion of said produced self-supporting body with another metal, thereby producing a macrocomposite body.
