Method for manufacturing a bonded body of a ceramic substrate and an aluminum-impregnated silicon carbide porous body

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a bonded body of a ceramics substrate and an aluminum-impregnated silicon carbide porous body in which the manufacturing cost can be reduced while ensuring good bonding.SOLUTION: Provided is a method for manufacturing a bonded body of a ceramic substrate and an aluminum-impregnated silicon carbide porous body in which aluminum or an aluminum alloy is impregnated in a porous body made of silicon carbide. In the method, as a bonding material, a double sided brazing clad material in which a brazing material layer containing 3.0 mass% or less of magnesium on both surfaces of a core material made of an aluminum alloy is formed, is interposed between the ceramic substrate and the aluminum-impregnated silicon carbide porous body and heated to a bonding temperature in a non-oxidizing atmosphere.SELECTED DRAWING: Figure 1
