    • A cycle of electroplating is repeated in an electroplating bath containing at least one metal ion selected from cobalt, nickel and iron, a buffering agent and a conducting agent by use of a soluble anode. The concentration of the conducting agent in an initially prepared electroplating bath is set at 70 to 95% of a saturated concentration. The electroplating is repeated in such a way that a first replenishment solution containing a buffering agent and a conducting agent at concentrations of 0.5 to 1.2 times the concentrations in the initially prepared electroplating bath and free of the metal ion is added so as to replenish the agents that have been reduced in amount during the course of the electroplating and a concentration of the conducting agent in the electroplating bath after the replenishment of the first replenishment solution is adjusted to 70 to 95% of a saturated concentration thereof. According to the invention, the electroplating can be repeated while keeping the electroplating bath over a long time in a good condition sufficient to provide a plated film having high throwing power and a good appearance, so that there can be stably obtained plated films over a long time without frequent regeneration such as by electrolysis for lowering the concentration of a metal ion in the plating bath, thus being good at economy.
    • 在含有选自钴,镍和铁中的至少一种金属离子的电镀浴,使用可溶性阳极的缓冲剂和导电剂中重复电镀循环。 将初始制备的电镀浴中的导电剂的浓度设定为饱和浓度的70〜95%。 重复电镀,使得添加含有缓冲剂和导电剂的浓度为初始制备的电镀浴中浓度为0.5至1.2倍且不含金属离子的第一补充溶液,以补充试剂 在电镀过程中已经减少量,并且在补充第一补充溶液之后将电镀浴中的导电剂浓度调节为其饱和浓度的70-95%。 根据本发明,电镀可以在保持电镀槽长时间的条件下重复进行,该条件足以提供具有高投掷功率和良好外观的电镀膜,从而能够长时间稳定地获得电镀膜 时间不频繁地再生,例如通过电解来降低电镀浴中的金属离子的浓度,从而经济。
