Abstract

In present work we report the synthesis of nanoporous surface using a copper-based alloy via leaching the less noble element-rich phase out of nanostructured ternary Cu-Hf-Zr alloys. The removal of Hf and Zr by mixed acid etchants in the chill-zone region of rapidly solidified ingots leads to the formation of a nano-roughened surface layer constituted of copper. The average pore and grain size of the obtained structure were shown to be less than 100 nm and 50 nm respectively. (C) 2015 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. (AU)
