Abstract The codeposition behaviour of the electrodeposited iron group alloy system, NiFe and NiCoFe, was studied in acid sulphate electrolyte. X-ray diffraction measurements revealed the existence of FCC phases. X-ray fluorescence analysis of the elemental composition in NiFe and NiCoFe coatings electrodeposited over copper substrate was also carried out. The result suggested that Ni is inhibited by the presence of Fe2z and Co2z ions. The properties of soft magnetic NiFe and NiCoFe coatings electrodeposited in the presence of saccharin and sodium lauryl sulphate additives were studied. Corrosion performance of these coatings in 3?5% NaCl solution was evaluated using impedance electrochemical techniques. The superior coefficient of friction of NiFeCo coatings was observed from block-on ring test.
