Corrosion Performance of Novel EZ43 Mg Alloys Enriched with Ce and Nd

CODEN: MPCACD

Abstract

Magnesium alloys are promising lightweight structural materials, but their poor corrosion resistance limits broader application. This study investigates the corrosion performance and microstructural evolution of a novel EZ43 magnesium alloy enriched with rare-earth elements (Cereium [Ce] and neodymium [Nd]). The samples were prepared by extrusion and subjected to corrosion testing in Hank’s solution to simulate physiological conditions. Electrochemical impedance spectroscopy, potentiodynamic polarization, and hydrogen evolution tests were performed alongside surface characterization by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction (XRD). Results revealed that Ce and Nd additions improved corrosion resistance and promoted the formation of a more stable protective layer. Among the samples, EZ43B exhibited the lowest corrosion current density (Icorr) and hydrogen evolution rate, indicating superior corrosion performance. These findings suggest that RE-doped EZ43 alloys offer significant potential for biomedical applications where lightweight and corrosion-resistant materials are required.
