Porous Metals Produced by Spacer Method as Ecomaterials

摘要

Porous metals, or metallic foams, are emerging ecomaterials that can be applied to structural use, shock absorber, filter, heat exchanger, etc. Their very low densities and peculiar deformation behaviors will facilitate the application. The control of pore characteristics such as porosity and pore size distribution can be successfully achieved by spacer method. In this paper, fabrication of porous aluminum via the spacer method is introduced and their excellent properties due to homogeneous pore characteristics are exhibited.
