In this study, the calcium phosphate (Ca-P) coating was deposited on a biodegradable magnesium alloy using the electrochemical deposition method with a view to controlling the degradation rate as well as enhancing the bioactivity. The coating morphology and chemistry were characterized using scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDXS), and x-ray diffraction (XRD). The resistance to electrochemical degradation, as a result of the Ca-P coating on the magnesium alloy, in modified simulated body fluid (m-SBF) was evaluated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The results of this study show that the Ca-P coating significantly decreases the degradation rate of the magnesium alloy, indicating the potential of the Ca-P coating to be used as a corrosion barrier for temporary implant materials. 6 Corrosion 68 ARTICULO Choudhary, L. 52636 187300 187300 0 0 0 0 255119 BAAB BAAB 2026-03-06 200059411 0 200059411 2026-03-06 00:17:05 2026-03-06 ARTICULO
