The calcium phosphate coatings were prepared by virtue of electrochemical deposition in order to improve the corrosion resistance of Mg-1.0Ca alloys in simulated body fluids. The chemical compositions, structures and morphologies of the coatings were investigated by energy dispersive spectroscopy (EDS), X-ray diffractometry (XRD) and scanning electron microscopy (SEM), respectively. The potentiodynamic electrochemical technique was employed to investigate the bio-degradation behavior of Mg-1.0Ca alloys with Ca-P coatings in Hank's solutions. The experimental results show that the deposited coatings predominately consist of flake-shape brushite (DCPD, CaHPO4ยท2H2O) crystallites. The corrosion resistance of the substrates with coatings is improved in Hank's solutions significantly.
