摘要: In this study, DCPD (Brushite, CaHPO4.2H2O) coatings were prepared on the surface of a Mg–Ca–Zn alloy using different current density (0.15–1.2 mA/cm2) and deposition time (5–90 min). The results revealed that with needle-like morphology was observed for between 0.15 0.4 mA/cm2, whereas plate-like obtained at above 0.8 mA/cm2. showed roughness increased increasing density. lowest corrosion rate 0.14 mm/year dense uniform coating at 0.4 mA/cm2, while further increase has deleterious effect resistance.
