Abstract
This porous aluminum sintered compact is a porous aluminum sintered compact in which a plurality of aluminum base materials are sintered together, and a Ti—Al-based compound is present in bonding portions at which the aluminum base materials are bonded together. It is preferable that a plurality of columnar protrusions protruding outwards are formed on an outer surface of the aluminum base material and the bonding portions are present at the columnar protrusions.
Claims6
A porous aluminum sintered compact in which a plurality of aluminum base materials are sintered together,
- wherein the aluminum base materials are composed of aluminum fibers and aluminum powder with a mixing ratio of aluminum powder in a range of 1.0 mass % to 10 mass %,
- molten aluminum inside the aluminum base material is ejected outwards and solidified in a sintering step so that columnar protrusions protruding outwards are formed on an outer surface of the aluminum base material,
- shapes of the aluminum base materials are maintained after being melted,
- the porous aluminum sintered compact includes bonding portions at which the aluminum base materials are bonded together through the columnar protrusions, and
- a Ti—Al-based compound is present in bonding portions.
