Abstract
Electrodeposited Ni-Fe coating is employed in many fields such as corrosion, wear, magnetic and electrical applications, and electrocatalytic materials. To improve the properties of Ni-Fe coating, a wide variety of properties for coatings can be achieved by selecting different electrodeposition parameters. In this
work, Ni-Fe coatings are deposited on copper substrates. X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and microhardness analysis are used to study the effects of boric acid on the morphology, phase structure, nickel content and microhardness of the coatings.
The results confirm that the XRD patterns of the alloy deposits reveal that there are a number of sharp
peaks in the images, indicating good crystallinity. The morphology of electrodeposited Ni-Fe coatings
shows that the grains are spherical in nature for all samples, and EDS analysis of Ni-Fe composite confirms that the reduction of Ni decreases with increasing boric acid concentration. Moreover, reducing the
concentration of boric acid in the Ni-Fe coating bath can lead to improved properties.
