The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization , potentiometric analysis , cyclic voltammetry and electrochemical impedance spectroscopy . x - ray diffraction was used to estimate the grain size of the annealed nc copper . field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
本文研究了用igc (惰性气体蒸发凝聚原位温压法)制备并真空退火到不同晶粒尺寸的纳米晶铜和微米晶铜(冷轧紫铜、电解铜)在酸性硫酸铜溶液和中性含氯溶液中，在自腐蚀状态和阳极极化状态下的腐蚀性能。使用了动电势极化、电位测定、循环伏安法( cv )和电化学阻抗谱( eis )等方法。 x -射线衍射( xrd )的方法用来估算纳米晶铜晶粒尺寸。
Cyclic voltammetry indicated that the reaction mechanisms of micro - and nc copper are identical , but the anodic peaks current density of nc copper is much lower than that of mc copper . the potentiometric analysis demonstrated that the pitting corrosion seemed to happen earlier on nc copper surface than on the mc surface . the xrd found cu2o on nc copper surface while no oxide was found on mc copper surface
阳极极化实验表明，纳米晶铜的致钝电位、致钝电流和维钝电流都比微米晶铜要低。循环伏安法表明两者的反应机理没有根本的区别，但对阳极电流峰的电流值来说，微米晶要高于纳米晶，阴阳极峰的距离来说，微米晶要近一些。
