镧盐型缓蚀剂对Cu-Zn-Ni铜合金在3.5% NaCl溶液中的缓蚀作用
Inhibition of Lanthanum Salts-containing Inhibitors for Copper-zinc-nickel Alloy in 3.5% NaCl Solution
摘 要
利用硝酸滴定试验、失重试验、动电位极化方法以及电化学阻抗谱技术, 研究了Cu-Zn-Ni铜合金稀土镧盐型缓蚀剂, 在3.5%NaCl溶液中的缓蚀作用。结果表明, 协同型缓蚀剂BTA(苯并三氮唑)+TTA(甲基苯并三氮唑)和BTA+LaCl3能够很好地提高该铜合金在3.5% NaCl溶液中的耐腐蚀性能。当缓蚀剂中同时含有BTA、TTA、LaCl3(BTA:3 g·L-1, TTA:14 g·L-1, LaCl3:7 g·L-1)时所表现出来的缓蚀效率最高。Cu-Zn-Ni合金经BTA+TTA+LaCl3缓蚀剂处理后, 在NaCl溶液中室温下的腐蚀速率为2 μm/a。

Abstract
The lanthanum chloride-containing corrosion inhibitors for copper-zinc-nickel alloy were investigated by using corrosion resistance rapid test, weight loss experiment, potentiodynamic polarization measurement, and electrochemical impedance spectroscopy(EIS) study. The results indicate that the synergistic inhibitors of BTA+TTA or BTA+LaCl3 provide very good protective efficiencies for the copper alloy in 3.5% NaCl solution. The mixture of BTA, TTA and lanthanum chloride (BTA:3 g·L-1, TTA:14 g·L-1, and LaCl3:7 g·L-1) provided the highest protective efficiency. The corrosion rate of the Cu-Zn-Ni alloy with the BTA+TTA+LaCl3 inhibitor treatment in 3.5% NaCl solution at room temperature was evaluated to be 2 μm/year.
