A method for galvanically depositing nickel, cobalt, nickel alloys or cobalt alloys in a galvanic bath includes using electrolytes containing nickel compounds or cobalt compounds. At least one anode and at least one cathode of the bath are subject to periodic current pulses. The IA/IC ratio of the anode current density IA to the cathode current density IC is selected to be greater than 1 and smaller than 1.5, where the anode current density IA and the cathode current density IC are defined as current densities with respect to a deposition body on which deposition occurs during the application of periodic current pulses where the deposition body serves as anode and cathode respectively. The charge ratio QA/QC=TAIA/TCIC of the charge QA, transported during anode pulse of duration TA, to the charge QC transported during a cathode pulse of duration TC, is between 30% and 45%. A bath for carrying out the method may have contoured anodes, current restrictors, a cleaning device for the electrolyte, and a circulating device with recycling of the electrolyte through nozzles. |
