Effect of Ni Concentration in Cu-Fe-Ni Alloys Coating on Mild Steel Substrate Prepared by Electrochemical Deposition

Mild steel has applications in construction, mechanical engineering, general-purpose fabrication, fencing, furniture components for different shapes, and other industries. Cu-Fe-Ni alloy coating with different concentrations of Ni was produced on low carbon steel substrate by electrodeposition in this research. Electrochemical deposition (also known as electrodeposition) is one of the most commonly used techniques for the preparation of adherent metallic coatings used to improve the different properties of the base material. The electrolytic bath contained the 31.92 gl-1 CuSO4, 54.2 gl-1 FeSO4, NiSO4.7H2O (0.00 gl-1, 14.04 gl-1, 28.08 gl-1, 42.12 gl-1) and 15.4 gl-1 H3BO3 as buffer to maintain pH at 3. The electrodeposition is done at suitable deposition parameters. The effect of Ni concentration on the surface morphology, structure, and mechanical properties of the coating was revealed by scanning electron microscope (SEM), X-ray diffraction (XRD) analysis with a 45 kV accelerating voltage and a 40 mA current, and Vicker hardness tester respectively. Obtained results showed that with the increase in Ni content, grain size increases from 65.898 nm to 94.770 nm and elongation decreases from 39.780% to 37.033% while the mechanical properties increase. The thickness of deposited Cu-Fe-Ni alloys has a decreasing trend of thickness with increasing Ni contents. The coating thickness decreased from 82.73 μm to 34.98 μm.
