中文摘要The bio-corrosion properties of Mg-Zn-Mn alloys with and without Y in Hank's solution at 37 degrees C were investigated by using electrochemical test and electrochemical impedance spectra (EIS). The results of open circuit potential (OCP) and polarization tests indicated that Y could reduce the cathodic current density. A passivative stage appeared in the Tafel curve of the Y containing magnesium alloy, indicating that a passivative film was formed on the surface of the Y containing magnesium alloy. EIS results showed that the Y containing alloy had higher charge transfer resistance and film resistance, but lower double layer capacity than the alloy without the Y element. The surface reaction product identification by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) showed that the surface corrosion products were hydroxide and phosphate (Mg(3)Ca(3)(PO(4))(4)) for Mg-Zn-Mn alloy and phosphate (MgNaPO(4)) for the Y containing Mg-Zn-Mn alloys. The XPS results also showed that a Y(2)O(3) protective film was formed on the surface of the Y containing magnesium alloy which contributed mainly to the low cathodic current density and the high resistance.
