【Abstract】 A new type of electroplating satin nickel process is put forward,and the effects of bath compositions and technological parameters to the coating appearance are studied.When using the satin nickel additives (WD 20) obtained from our experiments,a good appearance of satin nickel coating has been obtained in the conditions of medium temperature,wide current density and agitation-free.The solution composition in bath is stable and period of treatment is longer than other satin nickel plating.In addition,the electrochemical behavior of additives in the baths is also been studied,and the appearances of coatings were also scanned with SEM.更多还原
