摘要：

Electrochemical cathodic deposition has been widely employed for fabrication of Ca-P films onto surface of titanium. However, systematical and theoretical analyses for this process are rarely reported. In this study, a model of Ca-P nucleation for electrochemical deposition process was proposed based on classical crystallization theories of thermodynamics and kinetics. The obtained results from this model referred to that: the following results are obtained: the Ca-P phase precipitated on titanium is DCPD under lower loading current (I-0<0.5 mA) and shorter loading time (t<50 s); the preferential precipitated phase on titanium is OCP under higher loading current (I(0>)0.5 mA) and longer loading time (t>50 s). Inspiringly, this theoretical model was successfully validated with our experimental results analyzed through high-resolution TEM micrographs. (C) 2008 Elsevier B.V. All rights reserved.
