英文摘要	Performance of biomaterials was strongly affected by their sun ace properties and could he designed artificially to meet specific biomedical requirements. In this study, F-(F), SiO42-(Si), or HCO3-(C)-doped Ca-P coatings were fabricated by biomimetic deposition on the surface of biodegradable high-purity magnesium (HP Mg). The crystalline phases, morphologies and compositions of Ca-P coatings had been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The biomineralization and corrosion resistance of doped Ca-P coatings had also been investigated. The results showed that the Ca-P coating with or without doped elements mainly contained the plate-like dicalcium phosphate dehydrate (DCPD) phase. The doped F, Si, or C changed the surface morphology of Ca-P coatings after mineralization. Doped F enhanced the mineralization of Ca-P coating, and doped Si retarded the mineralization of Ca-P coating. However, H-2 evolution of HP Mg discs with different Ca-P coatings was close to 0.4-0.7 ml/cm(2) after two-week immersion. That meant that the corrosion resistance of the Ca-P coatings with different or without doped elements did not change significantly. (C) 2014 Chinese Materials Research Society.
