Patent ID: 8186565

Claim:
A method of bonding an aluminum-boron-carbon ceramic-metal composite comprising, a) forming a porous body comprised of particulates being comprised of a boron-carbon compound, b) forming a particulate layer of titanium diboride powder on a surface of the porous body, c) infiltrating the porous body with the particulate layer with aluminum or alloy thereof such that the aluminum-boron-carbon composite is formed such that the particulate layer is infiltrated with the aluminum or alloy thereof and bonded to the composite, wherein the particulate layer has an aluminum metal content that is at least about 10 percentage points greater by volume than the composite, and d) fusing the aluminum-boron-carbon composite to a metal or metal-ceramic body through the infiltrated particulate layer of titanium diboride, wherein the metal-ceramic body is a composite other than an aluminum-boron-carbon composite.
