【摘要】 采用主要含硫酸镍、次磷酸钠、表面活性剂、醋酸钠及柠檬酸钠的镀液对不锈钢试片进行化学镀镍,研究了硫酸镍和表面活性剂的浓度、镀液pH值及温度对沉积速度的影响,确定了这几项参数的较佳取值。结果表明:硫酸镍25 g/L、表面活性剂0.1 g/L、温度85℃、pH值4.6较为适宜,在该工艺条件下所得的镀层样品经弯曲、热浸和人工汗实验均合格。更多还原

【Abstract】 A electroless nickel plating on stainless steel was made by plating solution which contains nickel sulfate,sodium hypophosphite,surfactant,sodium acetate,sodium citrate.The Influences of concentration of NiSO4·6H2O,pH value,temperature and addition of surfactants on deposition rate were studied.The results show that the optimum operating condition is concentration of NiSO4·6H2O 25 g/L,temperature of solution being 85 ℃,pH value being 4.6 and addition of surfactants being 0.1 g/L.Bend test,heat immersion test and artificial sweat test were done for sample.更多还原
