A novel method for fabricating open-cell metallic and alloyed foams |
| 초록 |
A new fabrication process for generating open-cell metallic foams was developed by combining electrical explosion of wire (EEW) and electrospray (ESP) techniques. FeCrAl alloyed nanopowders prepared by EEW in ethanol were used as a starting material, and commercial polyurethane (PU) sponges were used as templates. FeCrAl foams were successfully fabricated with porosities greater than 90%. The porosity of the fabricated foams was controlled by spraying time during the ESP process. As spraying time increased from 1 to 5 h, porosity decreased from 97 to 90%. The resulting foam possessed a continuous open cell structure, which was dependent on the structure of the PU template. The proposed method may be useful in the future as a simple means to fabricate open-cell metallic and alloyed foams. |
