Based on the rare earth metal (REE) salt solution, the optimum parameter was selected by comparing the anti-corrosion property of anodic film. The structure, component and surface morphology of anodic film and cross-section were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM) coupled with Energy Dispersive Spectroscopy (EDS). The corrosion behavior was evaluated by immersion test. In this paper, a dense anodic film approximately 20 μm thick was prepared on a AZ91D magnesium alloy through anodic oxidation coating. The results show that the anodic films were mainly composed of Mg17Al12, Mg17La2, MgO and amorphous compounds. The best corrosion resistance was obtained with specimen anodized in solution containing both lanthanum nitrate and magnesium, whose corrosion resistance is approximately 3 times higher than that of as-received AZ91D magnesium alloy. 2014-02-24T12:56:19Z 2014-02-24T12:56:19Z 2012 Article Applied Mechanics and Materials, vol. 187, 2012, pages 210-214 1660-9336 http://www.scientific.net/AMM.187.210 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32138 en Trans Tech Publications |
