Preparation and characterization of nanostructured dibasic calcium phosphate coating on magnesium alloy wire

In this study, nanostructured dibasic calcium phosphate (DCP) coating was prepared on the surface of magnesium alloy via hydrothermal method. The nanomorphology of coating was characterized by scanning electron microscopy (SEM). Raman spectroscopy and X-ray diffraction (XRD) confirmed the DCP phase of coating. The potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) results prove that the nanostructured DCP coating can greatly enhance the anticorrosion performance of AZ31B Mg alloy in PBS solution.
