电沉积钙磷盐涂层及其影响因素的研究

Study on the preparation of calcium phosphate coatings on Ti substrate by electrochemical deposition under different conditions

发展在低温下电沉积钙磷盐的方法,制备了可以提高医用钛表面生物活性的涂层。考察了电流密度和温度的变化对涂层性质和形貌的影响,并应用扫描电镜(SEM)、X射线衍射(XRD)、傅立叶-红外光谱(FT-IR)对合成的生物材料进行分析和表征,探明了电沉积钙磷盐涂层主要因素的影响作用。结果表明,反应温度可导致钙磷盐涂层的形貌和组成的变化,电流密度则影响钙磷盐晶体的生长方向。

In this work, calcium phosphate coatings were prepared by the electrochemical deposition technique, and the effects of reaction temperature and current density on the preparation were studied. The coatings were characterized by scanning electron microscopy （SEM）, X-ray diffraction （XRD） and fourier transform infrared spectroscopy （FTIR）. The results indicated that the temperature could affect the composition and structures of calcium phosphate coatings, but the current density affected the crystal growth mode and morphologies of the coatings.
