The dependence of the electrodeposition of Fe-Ni-Co alloys on hydrodynamics, current density and solution temperature using pulse and pulse reverse currents have been investigated. Deposit compositions with pulse current (PC) were similar to those obtained with pulse current (PC) between 20 and 200 Hz at higher peak cathodic and anodic current densities and higher temperatures resulted in deposits with lower Fe and higher Ni content than with either dc or PC. The appearance of deposits obtained by PC and PR were superior to those obtained by dc. Deposits were smoother and brighter at 55 degrees C than at room temperature, and were smoother and more adherent at higher rotation rates.
