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 （惰性氣體蒸發凝聚原位溫壓法）制備並真空退火到不同晶粒尺寸的納米晶銅和微米晶銅（冷軋紫銅、電解銅）在酸性硫酸銅溶液和中性含氯溶液中，在自腐蝕狀態和陽極極化狀態下的腐蝕性能。使用了動電勢極化、電位測定、循環伏安法（ cv ）和電化學阻抗譜（ eis ）等方法。 x -射線衍射（ xrd ）的方法用來估算納米晶銅晶粒尺寸。 -
