英文摘要：

Pd-Ni and Pd-Ag alloy nanowires arrays have been fabricated in the nanopores of anodic aluminum oxide template with 200 nm in diameter and 60μm in depth by galvanostatic electrodeposition. Scanning electron microscopy and Energy-dispersive X-ray analysis were employed to characterize the morphologies and compositions of Pd-alloy nanowires. Research results show that Pd-Ni alloy nanowire arrays with 7.89 % - 15.21% （mass） nickel can be fabricated by applying current density ranging from 0.6- 1.0 mA ·cm^-2 Nickel contents in Pd-Ni alloy nanowires will ascend with the increase of current density. Pd-Ag alloy nanowire arrays with 22.88% - 16. 55% （mass） silver can be obtained by applying current density ranging from 2. 0 - 3. 0 mA·cm^-2, the silver contents in Pd-Ag alloy nanowires will decrease with the increase of current density. SEM images show that the alloy nanowire arrays are continuous, parallel and well-aligned, compact crystal, with an aspect ratio of 250.
