چکیده انگلیسی
Duplex Ni coatings consisting of Ni-P deposits as primer layer and Ni-Sn-P deposits as outer layer were prepared on Mg alloy. These coatings exhibit uniform surface and improved corrosion resistance after adding trace stannous (II) chloride (SnCl2) into the outer layer plating bath. X-ray photoelectron spectroscopy proved the non-existence of Sn in the coating. The coating surface was characterized by scanning electron microscopy and atomic force microscopy. X-ray diffractometer patterns show that SnCl2 is favourable for amorphisation of the coating. The corrosion protection of the coating was confirmed by potentiodynamic polarisation and electrochemical impedance spectroscopy measurement.
