摘　　要：采用由100 g/L Ni_2SO_4·6H_2O、120 g/L NiCl_2·6H_2O、40 g/L导电盐、50 g/L H_3BO_3和适量BH-959系列复合光亮剂[按300 mL/(kA·h)补加]组成的镀液对铁基铰链滚镀镍。研究了温度、pH、施镀时间、滚筒转速及电流密度对滚镀镍液分散能力和镀层厚度的影响,得到最佳条件为:温度60°C,pH 4.4,电流密度4 A/kg,滚筒转速8 r/min,时间90 min。BH-959滚镀镍工艺在光亮剂消耗量、镀液分散能力等方面都优于行业同类工艺,目前该工艺已成功应用于广东某家具五金表面处理公司。Barrel nickel plating was conducted on iron hinge in a plating bath composed of Ni2SO4-6H2O 100 g/L, NiCl2·6H2O 120 g/L, conducting salt 40 g/L, H3BO3 50 g/L and BH-959 composite brightener as required and with a replenishment amount of 300 mL/（kA.h）. The effects of temperature, pH, plating time, rotation rate of barrel and current density on the throwing power of the barrel nickel plating bath and coating thickness were studied. The optimal conditions were obtained as follows： temperature 60 ℃, pH 4.5, current density 4 A/kg, rotation rate of barrel 8 r/min, and plating time 90 min. The BH-959 barrel nickel plating process is superior to other counterparts in the industry in respect of the consumption of brightener and the throwing power of plating bath. It has been successfully applied to a company in Guangdong professionalized in surface treatment of hardware for furniture.
