AbstractThe 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 (Mg-5(CO3)(4)(OH)(2)center dot 5H(2)O), monohydrocalcite (CaCO3 center dot H2O), kovdorskite (Mg-2(PO4)(OH)center dot 3H(2)O) and hydroxyapatite (Ca-5(PO4)(3)(OH)) constituted the corrosion products in which magnesium hydroxide was enriched in the inner layer, and dypingite and kovdorskite as the principal phases were enriched in the middle layer, while monohydrocalcite and hydroxylapatite as the minor phases accumulated in the outside layer.
