JOINING METHOD FOR METAL-CERAMICS COMPOSITE MATERIALS OR METAL-CERAMICS COMPOSITE MATERIAL AND METALLIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a joining method capable of easily joining metal-ceramics composite materials or a metal-ceramics composite material and a metal material without subjecting to heat treatment. SOLUTION: This joining method is for metal-ceramics composite materials which contains ceramics powder or fiber as a reinforcing material or aluminum or aluminum alloy as matrix. The composite materials have ceramics powder or fiber whose contents is 30 vol.% or less and aluminum or aluminum alloy whose composition is 12 wt.% or less in Si and 5 wt.% or less in Mg. The joining method is for both metal and ceramics composite materials wherein both composite materials are joined by the FSW method.
