摘要
An aluminum-boron-carbon (ABC) ceramic-metal composite bonded to a metal or metal-ceramic composite other than ABC composite is made by forming a porous body comprised of particulates being comprised of a boron-carbon compound that has a particulate layer of titanium diboride powder on the surface of the porous body. The porous body is infiltrated with aluminum or alloy thereof resulting in the simultaneous infiltration of the TiB2 layer, where the layer has an aluminum metal content that is at least about 10 percentage points greater by volume than the (ABC) composite. The ABC composite is then fused to a metal or metal-ceramic body through the infiltrated layer of titanium diboride, wherein the metal-ceramic body is a composite other than an aluminum-boron-carbon composite.
