| Abstract: |
| To improve further the corrosion resistance of 2024 aluminum alloy, the nickel coating was obtained by electroless plating technology,and the surface morphology was observed using scanning electron microscopy(SEM),and the corrosion behavior of 2024 aluminum alloy and the Ni-P coating was investigated by open circuit potential, polarization and electrochemical impedance spectroscopy(EIS). The tested results show that the Ni-P coating on aluminum alloy is compact. Compared to aluminum alloy, the free corrosion potential of the Ni-P coating is nobler, and the free corrosion current density is lower. Thus, Ni-P film improves the corrosion resistance of aluminum alloy. |
