【Abstract】 This paper studies a technology process of electroless nickel plating on aluminium.The pretreatment consists of cleaning, etching, rinsing, zincate. The relation between the plating rate and primary factors in electroless nickel plating is developed.It is found that increasing the concentrations of nickel sulfate and sodium hypophosphite,temperature and pH improves the plating rate.There is a maximum of plating rate with the complexing agent increasing. The plating rate,stability of bath,hardners and solderability of deposition are satisfactory when the technology is operated with optimum conditions which are:nickel sulfate 30 g/L,sodium hypophosphite 30 g/L,complexing agent 19g/L,temperature 90℃,pH 5, stabilizer 3 ppm.更多还原
