Fluoridated hydroxyapatite coatings (FHAP) were prepared on titanium substrate by electrochemical deposition technique containing Ca2+, PO4(3-), and F(-) ions. The deposition was all conducted at a constant current of 0.9 mA for 60 min at 60 degrees C. The as-prepared coatings were examined by scanning electron microscope (SEM), energy-dispersive Xray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and Xray diffraction (XRD) tests. The results indicate that the FHAP cryatals take the morphology of nanoscale-rodlike cone rather than the micron-daisy petal, and the composite coating becomes more compact. The FTIR test indicates that the symmetry of stretching and bending vibration modes of hydroxyl changed, simulated body fluid immersion test proved that the FHAP coating had induced carbonate-apatite formation, indicating that the composite coating possesses excellent biocompatibility.
采用含Ca2+、PO4(3-)和F(-)离子的电化学沉积技术在钛基底上制备了氟化羟基磷灰石涂层（FHAP）。沉积均在60℃下以0.9 mA的恒定电流进行60分钟。通过扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）、傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）测试对制备的涂层进行了检测。结果表明，FHAP晶体呈纳米级棒状圆锥形态，而非微米级雏菊花瓣形态，且复合涂层变得更加致密。FTIR测试表明羟基的伸缩和弯曲振动模式的对称性发生了变化，模拟体液浸泡试验证明FHAP涂层诱导了碳酸磷灰石的形成，表明该复合涂层具有优异的生物相容性。
