自1939年意大利人L.Cambi和R·Piontelli提出第一个氨磺酸镀镍专利以来,至今已有四十年的历史了,其间经过Cuper、Barrett、Diggin等人的发展,现已广泛应用于工业生产中。目前通行的有氨磺酸镍、氨磺酸镍氯化镍、氨磺酸镍溴化镍及高速镀镍四种类型的槽液,几十种适用于各种电镀需要的典型配方。 氨磺酸镀镍的槽液,因其工艺电流密度高(可达100A/dm~2),镀件的镀层性质优良、应力低、纯度高,良好的可再加工性,故具有独特的优点。目前为得到高结合强度(能经受温度、外应力、速度等骤变,镀后需进行机械加工)的镀层,在铝上直接镀、在塑料上电镀以及高速电镀、电铸等工艺中多采用氨磺酸镀镍。它虽是目前国外使用的一种先进工艺,但从
It has been 40 years since the Italian Patent L.Cambi and R Piontelli proposed the first patent for nickel sulfenate in 1939. In the meantime, it has been widely used by Cuper, Barrett and Diggin et al. In industrial production. At present, there are four types of bath sulfides, such as nickel sulfamate, nickel sulfamate, nickel nickel sulfamate and high-speed nickel plating, and dozens of typical formulations suitable for various plating needs. Because of its high process current density (up to 100A / dm ~ 2), the plating solution of sulfamic acid nickel plating has the unique advantages of good coating quality, low stress, high purity and good reworkability. . Currently in order to obtain high bonding strength (can withstand temperature, stress, velocity and other sudden changes, after plating need to be machined) plating, direct plating on aluminum, plastic plating and high-speed electroplating, electroforming and other processes used more Sulfamic acid nickel plating. Although it is an advanced technology used abroad, but from
