摘要: Biodegradable magnesium alloys have been widely investigated in the field of biomaterials because they can be gradually dissolved and absorbed by human body without long-term existence. However, it was found that bare implants suffered from rapid corrosion. Surface modification is applied to improve corrosion resistance biocompatibility implants. In this study, Ti-O/HA composite coatings including typical flakes nanofibers were fabricated on Mg-Zn alloy. The Ti-O films deposited alloy direct current magnetron sputtering, subsequently coated with HA electrochemical deposition, respectively. obtained X-ray diffraction, Fourier Transform Infrared spectroscopy scanning electron microscopy. evaluated potentiodynamic polarization hydrogen evolution tests simulated fluid at 37 °C. results show compact are composed particles within size 100 nm, outermost predominantly doped Na+, Mg2+ ions functional groups. stronger diffraction broader peak than around 25.8° ascribed preferential growth orientation (002). morphology changed into addition NaF, mechanism explain difference also discussed. improved significantly coatings, rates 10 days 4.13, 1.77, 0.96 0.85 mm/y, Copyright © 2011 John Wiley & Sons, Ltd.
