On the basis of the unique primary formation and growth behaviors of nickel layers on the micro-arc oxidation coating of magnesium alloys,the catalytic activity of micro-arc oxidation coating on the electroless nickel plating as well as the evolutions of growth ways of nickel layers was explained. Moreover,the interfacial structure,corrosion resistance and electric conductivity of micro-arc oxidation/electroless nickel composite coatings were characterized. Finally,the application prospect and research direction of micro-arc oxidation/electroless nickel plating composite treatment were predicted in the filed of multifunctional surface modifications on magnesium alloys.
