Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The porous aluminum sintered compact according to claim 1 , wherein the Ti—Al-based compound is Al3Ti. 3. The porous aluminum sintered compact according to claim 1 , wherein a porosity is set to be in a range of 30% to 90%. 4. The porous aluminum sintered compact according to claim 2 , wherein a porosity is set to be in a range of 30% to 90%. 5. The porous aluminum sintered compact according to claim 1 , wherein the bonding portion is formed by at least two columnar protrusions. 6. The porous aluminum sintered compact according to claim 1 , wherein the columnar protrusions are significantly smaller than the aluminum fibers.
