Abstract

ABSTRACT Selective anodic dissolution of pre-galvanized surfaces was used to obtain nano-porous layers of approximately 10 microns thick on copper and silver specimens. To achieve single-phase homogeneous thermal diffusion layers of Cu5Zn8 and Ag5Zn8, we used a zinc plating process carried out in molten eutectic (KCl–NaCl–ZnCl2) at Т = 370°С. Dealloying of these coatings in a deep eutectic solvent (choline chloride/urea + 0.1 mol/l ZnCl2) at T = 133°C produced a typical bi-continuous structure of pores and ligaments (100 nm) on the surface of the silver and the copper.

在深度共晶溶剂中通过热扩散涂层Me5Zn8（Me=Ag，Cu）的脱合金在银和铜表面上形成纳米多孔层

摘要预镀锌表面的选择性阳极溶解用于在铜和银样品上获得约10微米厚的纳米多孔层。为了实现Cu5Zn8和Ag5Zn8的单相均匀热扩散层，我们使用了在熔融共晶（KCl–NaCl–ZnCl2）中以Т = 370°С。这些涂层在深共晶溶剂（氯化胆碱/尿素）中的脱合金 + 0.1 mol/l ZnCl2）在T = 133°C产生了典型的孔和韧带的双连续结构（100 nm）。图形摘要
