Electrochemically Deposited Calcium Phosphate Coatings Using a Potentiostat of In-house Design and Implementation

The effect of growth conditions and post treatments on the properties calcium phosphate films electrodeposited by a potentiostat authors’ design construction is presented. electrolyte used was formed with 0.025 M (NH4)H2PO4 0.042 Ca(NO3)2.4H2O, its pH kept at 5. A voltametric analysis performed to determine necessary potential values obtain films. Additionally, temperature varied influence deposited were characterized Fourier transform infrared spectroscopy, X-ray diffraction scanning electron microscopy. -1.4 V -1.7 present brushite phase. thermal post-treatment favored formation octagonal in amorphous phase, while basic treatment provided OH- groups for hydroxyapatite. low cost implemented presents excellent characteristics obtaining similar those obtained conventional potentiostat.
