Abstract

Electrodeposition process of calcium phosphate (CaP) was performed at various temperatures on AZ31 magnesium alloy and the influence on corrosion resistance of the alloy covered by CaP was investigated by electrochemical tests supported by photodocumentation. The electrodeposition treatment was performed by potential controlled method in water solution of Ca(NO3)2.4H2O, NH4H2PO4 and H2O2. The difference in the process of CaP formation at various temperatures was described using diagrams of current density time dependence. Corrosion measurements were performed in 0.9% NaCl solution at 22 ± 2 °C using electrochemical impedance spectroscopy. According to corrosion resistance results, the optimal temperature for CaP electrodeposition process was chosen.
