Calcium Phosphate Film Coating On Titanium Substrate By Electrochemical Deposition, D P. Kashima, A Rakngarm

Journal of Metals, Materials and Minerals

Calcium phosphate film on titanium substrate was achieved by electrochemical method in four different kinds of electrolyte. The pure titanium metal (99.99%) with 0.8 cm in width and 2 cm in length was used as a substrate and it was subsequently etched by 2M HF for 1 minute before electrochemical deposition. Calcium phosphate film could form at a different current density for each kind of electrolyte as follows: 10 mA/cm2 for MCPM based aqueous solution, 20 mA/cm2 for MCPM based aqueous solution with ions addition, 10 mA/cm2 and 20 mA/cm2 for MCPM based 20%V/V ethanol and 50%V/V ethanol solution, respectively. …
