摘要
研究了在化学镀NiP合金镀层时,采用无机盐复合加速剂降低镀液温度、提高沉积速度的方法。结果表明,在普通化学镀NiP合金镀液中添加无机盐复合加速剂HN3(3份(NH4)2SO4与2份K2CO3的混合物)30g/L,在80℃下施镀,其沉积速度可达15μm/h,比不含该加速剂时提高40%左右,镀液寿命可达5个周期以上,镀层外观光亮,结晶细致。
In the processing of electroless Ni P alloy coating, inorganic composite accelerant was used to reduce operational temperature and not to reduce deposition rate. By comparing experimental results, it was shown that the inorganic composite HN 3((NH 4) 2SO 4/K 2CO 3=3/2) is an appropriate accelerant. Adding the HN 3 accelerant 30 g/L into the ordinary bath of electroless Ni P alloy at 80 ℃, the deposition rate can reach 15 μm/h that is 40% higher than that in the absence of HN 3 accelerant. The life of the bath can maintain over 5 cycles. The coated films have bright appearance and compactive grain.
