Cu-Zn合金去合金化法制备纳米多孔铜研究
|
摘要
采用感应熔炼、均匀化处理和电火花线切割及轧制工艺制备Zn含量(原子分数,at%)为25%的Cu-Zn合金前驱体,然后通过化学腐蚀和电化学恒压腐蚀去合金化得到纳米多孔铜材料。研究不同退火温度、化学腐蚀和电化学腐蚀时间对多孔铜孔隙率及形貌和尺寸的影响。结果表明:经800℃均匀化退火后制备的纳米多孔铜的孔隙分布比较均匀,孔隙率较高,且纳米铜的孔径尺寸主要在100nm~200nm之间;当腐蚀电压为5V,腐蚀时间在10min~15min时电化学恒压腐蚀去合金化速度快获得的纳米多孔铜的效果好。
Alloy of Cu-Zn with Zn of 25%atom fraction was prepared by induction melting,homogenized annealing,wire-electrode cutting and rolling technology.The nanoporous copper materials were obtained by chemical corrosi on or electrochemical corrosion dealloying.The effect of annealing temperature and corrosion time on porosity,morphology and size of nanopoporous copper was studied.The results show that the shape of the hole is uniform and porosity is higher when annealing temperature is 800℃,with the size of nanopore from 100 to 200 nm.When voltage is 5 Vand corrosion time is 10 to 15 min,nanoporous copper obtained by electrochemical corrosion is the best.
