摘要： An improved process and composition for the preparation of nickel or nickel alloy electrodeposits is provided. The process involves passing current from a anode to a cathode through an aqueous acidic electroplating solution containing zinc ions as impurities with the combination of at least one nickel compound, saccharin, and a sulfonated acetylenic compound or salt thereof, particularly propyne sulfonic acid.The invention is particularly useful for electroplating nickel onto a zinc die cast substrate, where zinc ion impurity build-up in the bath occurs.
摘要翻译：提供了用于制备镍或镍合金电沉积物的改进方法和组合物。该方法包括将电流从阳极通过含有锌离子作为杂质的含水酸性电镀溶液与至少一种镍化合物，糖精和磺化炔属化合物或其盐，特别是丙炔磺酸的组合相结合。本发明特别可用于将镍电镀到锌压铸基底上，其中发生在浴中的锌离子杂质积聚。
