Abstract:
A method of manufacturing a joint body constructed of at least one pair of substrates, each substrate comprised of a composite including (a) an aluminum matrix or an aluminum alloy matrix, and (b) a reinforcing ceramic, in which each joint surface of each of said substrates is put into contact with the other, an infiltrating material comprising an aluminum alloy containing at least 70 mol % aluminum is put into contact with at least one of the substrates, wherein the substrates and the infiltrating material are subjected to a heat treatment in a high level vacuum at a temperature such that both the aluminum matrix or aluminum alloy matrix, and the infiltrating material, melt, to infiltrate the aluminum alloy constituting the infiltrating material into the substrate, and the melted aluminum or aluminum alloy is diffused across each joint surface of each substrate.
