Abstract
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.
