Characteristic and Corrosion Studies of Rare Earth (Ree) Based Anodizing on AZ91D Magnesium Alloy
Abstract
<jats:p>Oxide coatings on AZ91D magnesium alloy were prepared using anodizing technique with 10mA/cm<jats:sup>2</jats:sup> current density for 5 minutes in electrolyte containing La (NO<jats:sub>3</jats:sub>) and Mg (NO<jats:sub>3</jats:sub>),with NaVO<jats:sub>3</jats:sub> as an additive. The corrosion behaviors of different coatings condition were evaluated by immersion test in 5.0% NaCl electrolyte for 72 hours. The microstructures were analyzed by Optical Microscope (OM) and Scanning Electron Microscope (SEM). It was found that coatings with the addition of NaVO<jats:sub>3</jats:sub> produced homogeneous primary α-matrix and bigger β-phase (Mg<jats:sub>17</jats:sub>Al<jats:sub>12</jats:sub>) compared to untreated AZ91D magnesium alloy. The oxide film formed by anodizing in electrolyte with NaVO<jats:sub>3</jats:sub> enhances the corrosion resistance of the AZ91D magnesium alloy significantly</jats:p>
