Abstract Mg_68-xZn₂₈Ca₄Nd_x(x=0,0.5,1,1.5)amorphous alloys with diameter of 2 mm were prepared by copper die spray-casting in vacuum. and research emphasis was put on the impact of Nd addition on the glass formation ability and corrosion resistance of the alloy. Specifically, the microstructure and composition of the amorphous alloy after immersion in the simulated body fluid for various duration were observed and analyzed by scanning electron microscopy (SEM) and energy spectrum analysis(EDS). The phase composition and glass formation ability of the alloy were investigated by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). Furthermore, electrochemical workstations was employed to test the electrochemical performance of the amorphous alloys in simulated body fluids. The research results have demonstrated that the glass formation ability of the alloy declined with the growing addition amount of Nd. Particularly, α-Mg phase precipitated on the amorphous matrix, when the addition amount of Nd were 1.0% and 1.5%. Accordingly, the alloy samples varied from pure amorphous structure to mix structure of crystalline and amorphous. Consequently, the Mg_67.5Zn₂₈Ca₄Nd_0.5 amorphous sample exhibits the best corrosion resistance.
