摘要
采用电化学测试和浸泡失重实验,对比分析了0.1mg/g Na2S、1%Na3PO4、5000mg/L Na2MoO4、及其复配0.1mg/g Na2S+1%Na3PO4、1%Na3PO4+5000mg/L Na2MoO4几种缓蚀剂的添加对10CrSiNiCu(907)钢-ZL102铝合金偶合体(后称钢-铝偶合体)的缓蚀效果。结果表明:几种缓蚀剂的加入均能在一定程度上减弱钢-铝偶合体的电偶腐蚀,并减缓了钢、Al各自在3%NaCl溶液中的腐蚀,其中复配体系(1%Na3PO4+5000mg/LNa2MoO4)对钢-铝电偶对的综合缓蚀效果最好。
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.
