Abstract

ZrO2-CaO 95%-5% as a ceramic biomaterial facilitates the osteoconductivity in new bone formation around implant. Surface characterization before and after electrochemical testing was performed used scanning electron microscopy (SEM). ZrO2-CaO coating was performed using a Sulzer Metco 9MCE Atmospheric Plasma Spraying facility. The electrochemical properties of the calcium oxide stabilized zirconium oxide coated and uncoated MgCa sample at the open circuit potential at different immersion time in Ringer’s solution were studied by electrochemical impedance spectroscopy (EIS). Equivalent circuit (EC) was used to modeling EIS data, in order to characterize ZrO2-CaO coated and uncoated MgCa surface..

Keywords
