Abstract
The corrosion evolution of pure magnesium implanted in femur bone of the rabbit was monitored by electrochemical impedance spectroscopy (EIS). The surface and cross-section morphologies, chemical compositions, phases and elemental distributions of the corrosion products formed on the implanted pure Mg were analyzed by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and electron probe micro-analyzer (EPMA), respectively. The results showed that the corrosion resistance of the implanted pure Mg decreased first and then increased with the implantation time. Magnesium hydroxide (Mg(OH)2), dypingite (Mg5(CO3)4(OH)2
