| Abstract: | Mg alloy MB8 was surface-modified by micro-arc oxidation (MAO).Several organic coatings were prepared on the micro-arc oxidation coating of the Mg alloy.Electrochemical workstation IM6e was used to measure the electrochemical steady state I/E polarization curves and Tafel slope of the micro-arc oxidation coating in combination with organic coatings.The results show that the organic coatings can increase various degrees of the corrosion resistance of the ceramic layer by micro-arc oxidization of the Mg alloy.Especially,the corrosion resistance of sample which used multi-technics of seal is best. |
| Keywords: | micro-arc oxidization corrosion resistance cathode-electrophoresis polarization curve Tafel slope |
