| Objective To improve the corrosion resistance of 5083 aluminum alloy used for drone. Methods The polarization, electrochemical impedance spectrum and energy dispersive spectrometer were employed to study the effect of sodium molybdate inhibitor on the corrosion resistance of 5083 aluminum alloy in 3% NaCl solution. Results After addition of sodium molybdate in the 3% NaCl solution, the corrosion potential was decreased and separated from the pitting potential, the passivated current was reduced, the impedance was increased, and the capability of inhibiting pitting was promoted. Conclusion Sodium molybdate had corrosion inhibition effect on 5083 aluminum alloy. |
