摘要:

采用微弧氧化技术(MAO), 以纯钛(TA2)为基体, 在醋酸钙和磷酸二氢钠电解液体系中, 制备含羟基磷灰石(HA)的生物活性陶瓷膜, 并利用扫描电子显微镜(SEM)、 X射线衍射(XRD)、 X射线[KG*8]能谱(EDS)和红外光谱(FTIR)对膜层进行表征, 通过体外模拟体液浸泡实验检测膜层的生物活性. 结果表明, 纯钛经微弧氧化处理10 min后, 在其表面能生成一层含羟基磷灰石成分的多孔陶瓷膜, 该膜层经模拟体液浸泡48 h后, 其表面覆盖一层含有CO2-3的羟基磷灰石(类骨磷灰石), 即该陶瓷膜层具有良好的生物活性.

Abstract:

Porous hydroxyapatite(HA)ceramic coating on pure titanium (TA2) substrate was fabricated by microarc oxidation (MAO) in electrolytic solution containing calcium acetate monohydrate and sodium biphosphate dihydrate salt. The morphology, phase and composition of the coating were characterized by scanning electron microscopy (SEM), Xray diffraction (XRD), energy dispersive Xray spectrometry (EDS) and Fourier transmission infrared spectrometry (FT-IR). The bioactivity of the HA ceramic coating was investigated by simulated body fluid (SBF) tests in vitro. The result shows that the ceramic coating was formed on pure titanium substrate, and hydroxyapatite phase was found in the ceramic coating after the microarc oxidation for 10 min. Moreover, HA ceramic coating was proved to be of excellent bioactivity from the carbonatecontaining HA formation on the ceramic coating surfaces. The coatings of MAO are covered completely by the carbonatecontaining HA ceramic coatings after 48 h exposure to simulated body fluid.
