Abstract

Recent development of fabrication methods of porous metals with open channels are introduced. Open-channel aluminum was fabricated by extracting template wires coated with lubricant out of solidified aluminum. The lubricant serves as a diffusion barrier between template wire and its surrounding aluminum. The penetration ratio of the through-holes is 100%. The hole size, hole length and porosity are uniquely controlled by thickness, length, and the number of template metallic wires, respectively. The methodology for producing the open-channel metals is expected opportunities for application technologies such as functional materials like heat sinks, heat exchangers, shock absorbing materials and light-weight structural materials.
