镍铁合金电镀工艺近年来有较大发展,并得到了广泛的实际应用。实践证明,镀层为含铁20～45％的光亮镍铁合金,其性能与亮镍镀层相同,甚至更好;尤其是用铜或黄铜打底,含铁量为20～45％的合金镀层,厚度小于12.7微米(如2.54微米)时,其效果比用同样厚度的亮镍镀层更好。为了节约更多的金属镍,目前各国都在努力研究把镍铁合金镀层中的铁含量提高到最大值。国内最近的研究成果表明,在以镍铁合金电镀液为基的复合电镀工艺中
Ferroalloy electroplating process in recent years have made great progress, and has been widely practical application. Practice has proved that the coating is 20 to 45% ferrous nickel-iron alloy with the same performance and bright nickel coating, or even better; especially with copper or brass base, the amount of 20 ~ 45% iron alloy coating, Thicknesses less than 12.7 microns (eg, 2.54 microns) are more effective than bright nickel coatings of the same thickness. In order to save more nickel metal, all countries are trying hard to study the iron content in the nickel-iron alloy coating to the maximum. Recent domestic research shows that in the nickel-iron alloy plating solution based composite plating process
