Influence of the Alloying Elements on the Corrosion Behavior of As-Cast Magnesium–Gallium–Zinc Alloys in Simulated Body Fluid

The in vitro corrosion rate of as-cast ternary Mg-Ga-Zn alloys simulated body fluid (SBF) was evaluated. effects Ga3+ and Zn2+ on the formation, growth stability Ca, P-rich compounds surface alloys, effect these rate, were studied. Ternary (Ga from 0.375 to 1.5 wt% Zn 6 wt%) obtained then immersed SBF evaluate using weight loss method. species formed characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FT-IR). formation amorphous observed. are related ions released into SBF. Mg, Ga during process studied play an important role Posner’s clusters, propitiating reduction size agglomerates. increased as intermetallics increased. amount depend concentration alloys.
