概要
- 論文の詳細を見る
Porous aluminum with well-adjusted porosity and pore size was fabricated by a powder-metallurgical spacer method, and its fluid conductivity was investigated. As the porosity and pore size increased, the Darcian permeability increased. However, the permeability of the porous aluminum was significantly lower than the expected value based on those of other similar porous materials. The low fluid conductivity is attributed to the presence of small apertures at cell walls, which is peculiar to the porous metals fabricated by the powder-metallurgical spacer method.
