Paper Title:
Corrosion Characteristics of PEO Films on AZ31 Magnesium Alloys
  Abstract

The aim of this work is to discuss the corrosion characteristics of plasma electrolytic oxidation (PEO) films formed on AZ31 magnesium alloys in alkaline silicate solution. The uniform and pitting corrosion resistance of the PEO films was investigated by potentiodynamic polarization tests and potentiodynamic scanning curve tests. The composition, the structure and the element contents of the films after immersed in 3.5 wt.% NaCl solution for different time were investigated by XRD、SEM and EDS. The results indicated that the corrosion occurred on AZ31 magnesium alloy and treated PEO samples during five days immersion, but the corrosion tendency of the PEO treated samples is smaller than that of AZ31 magnesium alloy.
