摘要

通过电化学试验和质量损失试验，研究了几种缓蚀剂对907钢- zl102铝合金电偶在3%NaCl溶液中的缓蚀效果。抑制剂包括0.1 mg/g Na2S、1%Na3PO4和5000 mg/L Na2MoO4，以及它们的化合物0.1 mg/g Na2S + 1%Na3PO4和1%Na3PO4 + 5000 mg/L Na2MoO4。结果表明:所有缓蚀剂均能在一定程度上降低907钢- zl102铝合金联轴器的电偶腐蚀，减缓钢和铝在3%Na Cl溶液中的腐蚀;其中，1% Na3PO4+5000 mg/L Na2MoO4对907钢- zl102铝合金联轴器的综合缓蚀效果最好。

几种缓蚀剂对钢-铝偶合体在3%NaCl溶液中的缓蚀作用研究

The corrosion inhibition effect of several inhibitors on a galvanic couple of 907 steelZL102 Al alloy in 3%NaCl solution was investigated by using electrochemical tests and mass-loss experiment. The inhibitors include 0.1 mg/g Na2 S, 1%Na3PO4and 5000 mg/L Na2MoO4 as well as their compounds of 0.1 mg/g Na2S + 1% Na3PO4 and 1% Na3PO4+ 5000 mg/L Na2MoO4. The results showed that, all the inhibitors can reduce the galvanic corrosion of 907 steel-ZL102 Al alloy coupling to a certain extent, and slow the corrosion of steel and aluminum in 3%Na Cl solution; among others the integrated inhibition effect of the compound 1% Na3PO4+5000 mg/L Na2MoO4 is the best for the 907 steel-ZL102 Al alloy coupling.
