Abstract: The developed Mg-based metallic glass shows great potential as implants in biomedical applications instead of crystalline Mg alloys, which may possesses acceptable corrosion properties. In this study, corrosion behaviors of melt-spun amorphous Mg67Zn28Ca5 ribbons were investigated in physiological saline solution. Electrochemical testing and hydrogen evolution rate indicated that the glassy ribbons obtained at lower wheel speed were more noble with smaller corrosion current, and possessed a comparatively lower corrosion rate in physiological saline solution. Surface morphology analysis revealed that glassy Mg67Zn28Ca5 ribbons exhibited a strong susceptibility to localized pitting corrosion. A Zn-rich passive layer was formed on the surfaces of the glassy ribbons, indicating that Zn was an effective alloying element to enhance the corrosion resistance of amorphous Mg67Zn28Ca5 alloys.
