| Resumen | The galvanic corrosion of GW103 and AZ91D coupled to an Al alloy (Al 7005 [UNS A97005]) in an ethylene glycol (EG [C2H6O2]) solution at ambient (25°C) and elevated temperatures (90°C) was investigated using open-circuit potential (OCP), coupling potential (CP), galvanic current density, potentiodynamic polarization curve, and electrochemical impedance spectroscopy (EIS). Moreover, weight-loss measurement and scanning electron microscopy (SEM) also were used to investigate the galvanic corrosion damage of the coupled Mg alloys. The galvanic corrosion behaviors of the couples were compared in the EG solution before and after a combination of inorganic inhibitor sodium phosphate (Na3PO4) and organic inhibitor sodium dodecylbenzenesulfonate (C18H29NaO3S) was added to the solution. It was found that both the general corrosion and galvanic corrosion of the Mg alloys were mitigated by the organic-inorganic inhibitor package. The most interesting finding was that the anode and cathode of the Mg alloy-Al alloy couples were reversed by adding inorganic and organic inhibitors into the blank EG solution. The anode-cathode reversal can be attributed to the OCP changes of the anode and cathode after inhibitor addition. The measured galvanic behavior was in good agreement with the mixed-potential theory predictions. |
