Abstract

In order to further improve the degradation resistance and wear property of micro-arc oxidation (MAO) coating on magnesium alloys, nano-Y₂O₃ was added into the electrolyte to fabricate a nano-Y₂O₃-containing MAO coating. Microstructural characterization, wear test, electrochemical test, immersion test and cytotoxicity test were carried out. The results showed that there were mainly Ca₈MgY(PO₄)₇ and Y₂O₃ particles in the MAO coating. Ca₈MgY(PO₄)₇ could stabilize the coating and the nano-Y₂O₃ could seal the micro-pores. Therefore, both the degradation resistance and wear property of the coating were improved. The degradation rate decreased from 0.14 to 0.06 mm/a in Hank’s solution. The volume loss decreased from 0.46 to 0.27 mm³ at the same slip distance. MAO coating exhibited good biocompatibility with the cell relative growth rate (RGR) value of more than 90%. The nano-Y₂O₃-containing MAO coating thus has a good promising biomedical application.
