摘      要：A novel process for electrodeposition of hydroxyapatite coating on titanium substrate was developed. The mechanism of the electrochemical reaction on the cathode was changed by adding H2O2 into the electrolyte. The evolution of H2 gas was erased. And owing to the fact that H2O2 posesses high tendency of being reduced, a fairly high cathodic current can be gained at a more positive potential than -1.0V. During the electrodeposition, 6%H2O2 is added, the temperature of deposition is fixed at 55℃ and pH of electrolyte is adjusted to 5.5. Dense and homogeneous film is crystallized at high rate. The mechanism of crystallize process was discussed.
