Abstract. The development of novel, cytocompatibility metallic glasses is crucial for advancing next-generation biomedical implants. This research presents a comprehensive electrochemical investigation of the innovative Cu51Zr30Hf14Ag5 metallic glass, specifically evaluating its corrosion performance in alkaline environments to assess its potential for in vivo applications. The alloy was synthesized via melt-spinning, with its amorphous structure confirmed by X-ray diffraction. Its corrosion behaviour was rigorously analysed in NaOH solutions with varying pH using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Results demonstrated exceptional corrosion resistance in alkaline media. The formation of a stable passive film was validated by scanning electron microscopy and energy-dispersive spectroscopy. This study confirms the outstanding suitability of the Cu Zr Hf Ag system for biomedical applications, providing a foundational basis for its future use in implantology.
