| Popis: | In this work bulk metallic glasses of Zr55Al10Ni10Pd25, Zr50Al10Ni15Pd25 and Zr40Al10Ni25Pd25 in rod form s were prepared by copper mold casting technique. The glass-forming ability, thermal stability and corrosion behavior were examined with the aim to investigate the possibility of synthesizing nanoporous Pd(Ni) alloy structure which are exhibiting good electrochemical characteristics by the dealloying treatment of Zr-Al-Ni-Pd bulk metallic glasses in acid solution. After chemical treatments, the glassy rods exhibit open, three-dimensional, and separated nanopore s structure. The size of nanopores (NP) is increased with increasing Zr content due to the enhanced dealloying kinetics. |
