摘要 | AZ91D magnesium alloys were treated by micro arc oxidation (MAO) in silicate-containing electrolyte. The sample dimension, thickness, morphology and element distribution of the coatings were examined by micrometer with electronic digital display, thickness tester, scanning electron microscope (SEM) and electron-probe micro analyzer (EPMA), respectively. The coating growth was investigated by three methods, containing directly observing the boundary area, macroscopically calculating the coating and directly measuring the whole substrate. The results show a phenomenon that the coatings growing inward and outward is observed intuitively in cross-section morphology of the MAO coating on magnesium alloys through the first method, and it proves the most intuitive evidence to illustrate how the coating grows. By the second method, dimensional changes of the substrates and the coatings can be observed and measured visually and the results also show that the coatings grow inward and outward at the same time, with lager grow rate outward compared with that of inward. The results of the third method once again show the coatings grow inward and outward simultaneously and the dimensions growing outward is lager than that of inward under different times, but the growth rate of the whole coating gradually reduces. ©, 2015, Central South University of Technology.
