摘　　要：采用过硫酸铵−柠檬酸钠体系化学退镀坡莫合金纤维表面的铜层。研究了退镀液中不同组分的质量浓度和温度对退镀速率的影响,得到较佳的工艺参数为:过硫酸铵75~100 g/L,柠檬酸钠40~50 g/L,氯化钠30~40 g/L,温度30~35°C。在该条件下坡莫合金表面铜层完全退除,且对基体基本无腐蚀作用,退镀后的纤维丝自然分散、柔性极佳。Coper coating was chemically stripped from the surface of permalloy fiber in a solution primarily composed of ammonium persulfate and sodium citrate.The effects of mass concentrations of different constituents in the stripping solution and temperature on the stripping rate were studied.The process parameters were optimized as follows:ammonium persulfate 75-100 g/L,sodium citrate 40-50 g/L,sodium chloride 30-40 g/L,and temperature 30-35°C.The copper coating could be completely removed thereunder from the permalloy fiber surface without corrosive attack to it.The fibers dispersed naturally afterwards,showing excellent flexibility.
