摘要:
摘要： The biocompatibility of anodized titanium (TiO 2 ) was improved by electrophoretically deposited mineral (strontium (Sr), magnesium (Mg) and zinc (Zn)) substituted hydroxyapatite (M-HAP). The M-HAP layer was grown on the anodized Ti surface at different deposition temperatures (room temperature, 60 and 80 °C). The phases and morphologies of the M-HAP layers were influenced by the deposition temperature. The coatings were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy equipped with energy dispersive X-ray analysis (SEM-EDX). Also, the effects of temperature and the mineral substitution of Sr, Mg and Zn for Ca on the physiochemical and biological properties of the M-HAP coatings were evaluated by the mechanical strength, ion dissolution and proliferation, alkaline phosphatase (ALP) activity and osteogenic expression of osteoblast like cells MG66 (HOS). Thus, the M-HAP deposition of TiO 2 will serve as a potential candidate for orthopedic applications. 出版者： Royal Society of Chemistry (RSC) 出版日期： 2015-01-01 出處： RSC Advances, 2015-01, Vol.5 (73), p.58980-58988 資源來源： Royal Society of Chemistry 識別號： ISSN: 2046-2069 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/c5ra11037h
