Lotus-type Porous Metals: Properties and Applications |
초록 |
Lotus-type porous metals with long straight pores are fabricated by precipitation of supersaturated gas when the melt dissolving gas is solidified. The main features of lotus-type porous metals are as follows; (1) the pores are straight, (2) the pore size and porosity are controllable, and (3) porous metals with pores whose diameter is as small as ten microns can be fabricated. According to our recent study lotus-type porous metals exhibit unique physical properties such as high damping capacity and high thermal conductivity, and superior mechanical properties. Furthermore, lotus-type porous iron fabricated using a pressurized nitrogen gas instead of hydrogen exhibits superior strength. The lotus-type porous metals can be applied to various functional materials: (1) aeroengine cooling components and (2) heat sink because of their higher heat transfer capacity, (3) artificial bone because of intruding new bone tissue into open pores, (4) golf putter developed by utilizing the merit of sufficient damping capacity, etc. |
