Magnesium alloy surface protection solutions
Due to the poor of chemical activity and protection of magnesium alloys , as structural materials, It is need to do surface protection process
the surface treatment of magnesium alloy include electroplating nickel, electroless nickel plating, micro-arc oxidation, anodic oxidation etc.
Micro - arc oxidation and anodic oxidation coating corrosion resistance is good, but they are non-conducting,
Electroplating nickel coating has good appearance performance and corrosion resistance, because of the applied current, electroplating speed is relatively fast, However, for some parts with complex shapes, it is not possible to conduct full surface plating very well.
electroless nickel plating is a widely used surface treatment method in recent years. electroless nickel has the advantages of high hardness, good wear resistance, compact coating, good corrosion resistance and uniform coating thickness.
