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 (I0 < 0.5 mA) and shorter loading time (t < 50 s); the preferential precipitated phase on titanium is OCP under higher loading current (I0 > 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.
