化学氧化法制备表层含CuO的超细铜线及其电化学腐蚀行为研究
Preparation of Superfine Copper Wire Containing CuO by Chemical Oxidation Method and Electrochemical Corrosion Behavior
摘要
Abstract
The oxide CuO was prepared on the surface of the ultrafine copper wire by the chemical oxidation method.The phase composition and the surface morphology of the samples prepared by the different solution ratio and reaction time were studied.The influence of the electrochemical corrosion behavior was investigated by potentiodynamic polarization curve(PD)and electrochemical impedance spectroscopy(EIS).And the results show that the moment the ratio of the sodium hydroxide and the ammonium persulfate solution is 1∶1 for 1.0 h,the surface material of the sample obtained after 1.0 h hot sintering is CuO/Cu2O,and its surface microstructure is fragmented,which has good corrosion resistance.The formation of the oxide film on the copper surface inhibits the corrosion reaction and effectively inhibits the transfer and the diffusion of electrons at the interface.关键词
