硫酸铜浸蚀试验
Examples
- What color is copper sulphate solution
硫酸铜溶液是什么颜色？ - 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。 - In acid copper sulphate solution , the nc copper has a more negative corrosion potential which is decreasing with reducing the grain size and diffusion impedance was only found in the as - prepared and as - annealed at 180 ? nc copper due to the diffusion within the pores and channels on the surface . both the tafel plots and eis study demonstrated that the nc copper exhibits a higher corrosion current and lower polarization resistance than its mc couterpart
在酸性硫酸铜溶液中，纳米晶铜的腐蚀电位比微米晶铜要负，并且随着晶粒尺寸的减小而降低。 eis研究表明，未退火的和180退火的纳米样品中发现了扩散阻抗，与表面孔洞和通道中的扩散有关。极化曲线外推法和电化学阻抗研究都表明纳米晶铜的腐蚀电流比微米晶铜高，而极化电阻要低。
