Abstract

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.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 134 words
A method for producing a macrocomposite, comprising; providing at least one body to be infiltrated, said at least one body comprising at least one material selected from the group consisting of a loose mass of substantially non-reactive filler and a preform comprising a shaped substantially non-reactive filler; placing at least one formed body, comprising an electrically insulating material, within said at least one body to be infiltrated or adjacent to said at least one body to be infiltrated; providing a matrix metal such that when said matrix metal becomes molten, that matrix metal will spontaneously infiltrate said at least one body; spontaneously infiltrating at least a portion of said at least one body with molten matrix metal, whereby the spontaneously infiltrated body at least partially surrounds said formed body, thereby forming a macrocomposite body.
Claim 2
Independent Claim 134 words
A method for producing a macrocomposite, comprising; providing at least one body to be infiltrated, said at least one body comprising at least one material selected from the group consisting of a loose mass of substantially non-reactive filler and a preform comprising a shaped substantially non-reactive filler; placing at least one formed body, comprising an electrically insulating material, within said at least one body to be infiltrated or adjacent to said at least one body to be infiltrated; providing a matrix metal such that when said matrix metal becomes molten, that matrix metal will spontaneously infiltrate said at least one body; spontaneously infiltrating at least a portion of said at least one body with molten matrix metal, whereby the spontaneously infiltrated body at least partially surrounds said formed body, thereby forming a macrocomposite body.
Claim 3
Dependent Claim 19 words
The method of claim 1, wherein said at least one formed body comprises at least one electrically insulating conduit.
Claim 4
Dependent Claim 27 words
The method of claim 2, wherein said at least one electrically insulating conduit comprises at least one material selected from the group consisting of alumina and mullite.
Claim 5
Dependent Claim 18 words
The method of claim 2, wherein said at least one electrically insulating conduit houses an electrically conductive material.
