| Abstract: | With the known reactant and resultant,the basic mechanism on electroless nickel plating under different conditions was discussed by using chemical equations based on the law of mass conservation.The new reaction equation different from classic theory of electroless nickel plating was proposed.And then the efficiency behavior of sodium pypophosphite was found.The effect of electrolyte composition and plating parameters such as stabilizer,pH value,loadage,promoter and complexing agent on the mechanism was discussed by P—H chemical bond breaking theory.Finally the solutions on improving the rate of nickel plating were put forward. |
| Keywords: | electroless nickel plating efficiency of sodium pypophosphite chemical equations nickel plating mechanism rate of reaction |
