Effects of micro-arc oxidation coating on corrosion behavior of Mg-Y-Zn in simulated body fluid

摘要：

　　The application of magnesium and its alloy as degradable biomaterials is mainly confined due to its high degradation rates in physiological environment.This research focused on the effects of micro-arc oxidation (MAO) on biodegradable behavior of this Mg-Y-Zn magnesium alloy in simulated body fluid (SBF).The corrosion rates of alloys were gauged by means of hydrogen evolution volume measurement and weight-loss method.SEM was utilized to observe the surface of the magnesium alloy and the cross-section of oxidation coating layer before and after corrosion.The Mg-Y-Zn with thicker oxidation coating exhibited greater corrosion resistance during the immersion test for 240h.
