摘要
通过电镀工艺对比,证实了氨基磺酸盐镀镍工艺可以实现大电流快速电镀。给出了镀液配方及合理的工艺参数。电镀中氨基磺酸镍含量越高,则分散能力越高、结晶更细致、内应力更小;但当含量大于600g/L时,电流效率减小。氨基磺酸镍含量应控制在350～500g/L范围内为宜。尝试了将氨基磺酸盐镀镍工艺应用于钢带镀镍生产,保证了生产的进度。
By contrasting plating technologies,it was proved that sulfamate nickel plating technology can be performed at high current density and high speed.The bath formula and rational process parameters were given.The increase of nickel sulfamate concentration in plating bath increases the throwing power and decreases the grain size and internal stress of deposit.The current efficiency is decreased at nickel sulfamate concentration>600 g/L.The content of nickel sulfamate should be controlled in 350～500 g/L.The pre...
