Research on electroless plating of magnesium alloy and its additives

magnesium alloy;  electroless plating;  additives;  stability;  Deposition rate

The pretreatment process and nickel plating liquid formula of magnesium alloy electroless plating were selected, and the coating test obtained by the process showed that the alloy had strong corrosion resistance, high hardness, dense structure, good gloss and certain ductility; The experimental results show that yttrium and europium have a greater influence on the stability of the plating bath, and ammonium fluoride and sodium carbonate have a significant effect on the plating speed, especially when the Y4+ concentration is 3.0 g/L, the stability of the plating bath is the most, while the acceleration effect of sodium carbonate is the most obvious at about 02 g/L. In this paper, their influence mechanism is analyzed.
