Abstract: A top electrophoresis coating was deposited on the surface microarc oxidation (MAO)
modified ceramic coating on AZ31 magnesium alloy. Microstructure and corrosion resistance of
this composite coating were studied by SEM, electrochemical potentiodynamic polarization, and
acid corrosion test. The results showed that the composite coating with a top electrophoresis
coating on the surface of ceramic coating exhibited a better corrosion resistance compared with
the coating formed by chemical conversion film combined with electrophoresis process.
Corrosive ions could permeate into the substrate with corrosion time, and the composite coating
was firstly destroyed around the scratch. The formation of composite coating with a higher
adhesive force due to the porosity of the ceramic coating contributed to the improved corrosion
resistance property. © 2013 Wuhan University of Technology and Springer-Verlag Berlin
