摘要
从镁合金微弧氧化膜表面化学镀镍层特异初生与生长行为出发,解说了镁合金表面微弧氧化膜对化学镀镍催化活性及镍层生长方式的演变,表征了微弧氧化/化学镀镍复合层的界面结构、耐蚀性和导电性,展望了微弧氧化/化学镀镍复合处理在镁合金表面多功能改性方面的应用前景与研发方向。
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.
