Influences of additives saccarin, thioure and natrilaurylsulphate on the electrodeposition process of the alloy FeCoNi were investigated using polarization curves and energy disperse spectroscopy (EDS). Results show that saccarin increases the anomalous ratio of the couples Fe/Ni (TFe/Ni) and Co/Ni (TCo/Ni) while thioure influences on TFe/Ni, TCo/Ni slightly and natrilaurylsulphate decreases TFe/Ni, TCo/Ni remarkably. The results can be explained by the different adsorption processes of the additives.
