Effect of Nd on the corrosion behaviour of AM50 and AZ91D magnesium alloys in 3.5 wt.% NaCl solution Arrabal Durán, Raúl Pardo Gutiérrez Del Cid, Ángel Merino Casals, María Concepción Casajús, P. Paucar, K. Garces, G. The corrosion performance of AM50 and AZ91D alloys containing up to 1.5 wt.% Nd was investigated by electrochemical and gravimetric measurements in 3.5 wt.% NaCl at 22 C. The alloys were characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD) and surface potential maps. In Nd-containing alloys, formation of Al2Nd and Al–Mn–Nd intermetallic compounds reduced the volume fraction and modified the morphology of the b-Mg17Al12 phase. The addition of Nd improved the corrosion resistance of the alloys due to increased passivity of the surface film and suppression of micro-galvanic couples. 2025-09-22T11:17:17Z 2025-09-22T11:17:17Z 2012 journal article .
