Research on Tribological Property of Micro-arc Oxidation Film on AZ91D Magnesium Alloy

摘要：

　　Magnesium alloys were treated by micro-arc oxidation at a constant applied current density.The friction and wear properties were investigated by optical microscope and universal friction and wear tester in 3.5%NaCl solution.The result reveals that the film formed by micro-arc oxidation enhances the corrosion resistance of the magnesium alloys.The Ecorr of micro-arc oxidation film improved 94mV than the Ecorr of magnesium alloys matrix.Wear resistance of the film was weakened in 3.5%NaCl solution.The wear mechanism of film depends on the load.Abrasive wear was predominant at low load.Peeling wear was predominant at high load,which result from damage of the film adhesion.
