摘要

Abstract

Nanoporous gold as obtained by corrosion of alloys of gold and a less noble metal is a system with manifold applications. The process of dealloying

however

can result in partially porous samples

when dealloying conditions are not optimized with respect to composition and pre-treatment of the master alloy. In the present work

we investigate the dealloying interface between porous material and non-porous alloy in two samples

in which dealloying either stopped automatically or was interrupted manually. Reasons for unintended termination of dealloying in the former case are suggested.
