| 英文摘要 | The microarc oxidation (mao) coatings produced at different current frequencies on az91d magnesium alloys were studied systematically. the morphologies, thickness, corrosion performances, and tribological properties of the coatings were investigated by the scanning electron microscopy, the electrochemical measurement system, and ms-t3000 friction test rig, respectively. the results show that the structure of the coatings becomes denser, and thickness becomes thinner with the increase of the current frequency. it is also found that the corrosion resistance of the coatings produced at higher frequency is improved greatly and the difference of the corrosion current density becomes small with increasing current frequency, which is similar to that of the coating thickness. the tribological test shows that the friction coefficient decreases with increasing the current frequency and the wear resistance of the coatings is influenced by both the thickness and structures. all these results were explained by analyzing the growing process of the mao coating. |
