| Abstract: | An oxide film with good corrosion resistance was formed on AZ 91D magnesium alloy surface by nitric acid oxidation process.The micro-morphology of the oxide film on the magnesium alloy was analyzed and observed with scanning electron microscope.The effects of activation and oxidation time on the micro-morphology of the surface conversion film were systematically discussed.The results show that the surface of the oxide film formed when activation time is 0.5 min and oxidation time 2 min is uniform and integr... |
