Abstract To obtain high strength and good corrosion resistance of Mg-9Gd-4Y-1Nd-0.6Zr alloy, effects of Ce on microstructure and corrosion resistance of Mg-9Gd-4Y-1Nd-0.6Zr magnesium alloy was investigated by means of scanning electron microscopy, X-ray diffraction, corrosion mass loss test, electrochemical impedance spectroscopy and potentio-dynamic polarization test. The Mg alloy with 5% Ce shows better corrosion resistance. Its corrosion current density decreased about 55.6%. Its corrosion potential moved positive about 141 mV than that of Mg-9Gd-4Y-1Nd-0.6Zr alloy. Rare earth elements in the Mg alloy enriched along grain boundary as network distribution were caused by proper content of Ce. Corrosion resistance of the Mg alloy was enhanced by change of second phase particles. Their volume fraction in the Mg alloy surface increased higher and their sizes decreased than those of Mg-9Gd-4Y-1Nd-0.6Zr alloy.

Key words: Mg-9Gd-4Y-1Nd-0.6Zr magnesium alloy microstructure corrosion
