| 摘 要： | 应用原位椭圆偏振光技术考察了苯并三氮唑(BTA)覆盖层对铜合金的缓蚀作用.对高浓度Cl-条件下的铜合金线性电位扫描的原位掠射椭圆偏振实验表明,椭圆偏振参量△的变化滞后于电流变化,说明BTA覆盖层阻碍了腐蚀产物向溶液中的转移.随着腐蚀产物的不断聚积,阳极过电位增加,减小了腐蚀反应的电位差,从而减缓了腐蚀反应的速度,增强了铜合金的耐腐蚀能力.

| Abstract: | Inhibition BTA for copper alloy in high concentration chloride solution has been explored with in-situ graze ellipsometry and linear sweep voltammetry(LSV) technology.The results show that the change of parameter behind of current change and the shift of corrosion productions into solution were blocked by the BTA layer.With the corrosion production accumulated,the increase of overpotential on anode was necessary,and potential difference of corrosion reaction decreased.Thus the rate of corrosion reaction was delayed and the corrosion resistance of copper alloy was increased. |
