POROUS ALUMINUM COMPOSITE AND METHOD FOR MANUFACTURING POROUS ALUMINUM COMPOSITE

摘要

PROBLEM TO BE SOLVED: To provide a porous aluminum composite of high quality having an excellent joint strength between a porous aluminum body and an aluminum bulk body and to provide a method for manufacturing the porous aluminum composite.SOLUTION: There is provided a porous aluminum composite 10 which is formed by bonding a porous aluminum body 30 comprising aluminum or an aluminum alloy and an aluminum bulk body 20 comprising aluminum or an aluminum alloy, in which a Ti-Al-based compound is present at bonding parts 15 between the porous aluminum body 30 and the aluminum bulk body 20. Here, it is preferred that a plurality of pillar-shaped protrusions 32 protruding towards the outside are formed on one or both of the outer surfaces of the porous aluminum body 30 and the aluminum bulk body 20 and the outer surfaces have bonding parts 15 at the pillar-shaped protrusions 32.
