“…The thermal energy facilitates the ad-atoms diffusion and these atoms gain activation energy to occupy in the suitable places in the crystal structure [40][41][42]. This improves the surface smoothness and thus causes a decrease in the surface roughness of the film.…”

“…Permalloy, or an alloy based on Ni and Fe (less than 50 wt.%), is one of the most common soft magnetic alloys for practical applications due to the optimal combination of electrical, magnetic and operational properties [ 1 , 2 , 3 , 4 ]. The low cortical force, high magnetization and magnetic permeability in combination with almost zero magnetostriction make these materials attractive for use as magnetic-field sensors [ 5 ], electromagnetic shields [ 6 , 7 ], inductor cores for electromagnets [ 8 ], magnetic recording heads [ 9 , 10 , 11 , 12 ], inductor cores [ 13 , 14 ], microwave noise filters [ 15 , 16 ], tunable noise suppressors [ 17 ] and much more.…”

NiFe films with a composition gradient are of particular interest from the point of view of fundamental science and practical applications. Such gradient magnetic structures may exhibit unique functional properties useful for sensory applications and beyond. The issue surrounds the anomaly concerning the compositional gradient formed near the substrate in electrolytically deposited binary and ternary iron-containing alloys, which has not previously been clearly explained. In this work, light is shed on this issue, and a clear relationship is found between the structure and surface properties of the substrate, the initially formed NiFe layers and the film composition gradient.

“…Apart from electrodeposition parameters, the substrate's microstructure, especially the presence of high-energy (active) sites on edges, corners, kinks, and screw dislocation also effectively influence the shape, size, and morphology distribution of the micro-/nanostructures that are formed during electrocrystallization [26]. Therefore, many studies were performed to evaluate the effect of substrate microstructure on the hierarchical structure of the electrodeposited film, and consequently on properties, such as magnetic [27,28] and tensile properties [29], and its catalytic activity [30]. Changes in substrate-surface morphology and consequently the structure of the electrodeposited films were expected to affect the overall corrosion resistance of nickel layers [31,32].…”

In the present study, the impact of copper substrate grain size on the structure of the succeeding electrodeposited nickel film and its consequent corrosion resistance in 3.5% NaCl medium were evaluated before and after functionalization with stearic acid. Nickel layers were electrodeposited on two different copper sheets with average grain size of 12 and 25 µm, followed by deposition of stearic acid film through self-assembly. X-ray diffraction analysis of the electrodeposited nickel films revealed that the deposition of nickel film on the Cu substrate with small (12 µm) and large (25 µm) grains is predominantly governed by growth in the (220) and (111) planes, respectively. Both electrodeposited films initially exhibited a hydrophilic nature, with water-contact angles of 56° and <10°, respectively. After functionalization with stearic acid, superhydrophobic films with contact angles of ~150° were obtained on both samples. In a 3.5% NaCl medium, the corrosion resistance of the nickel layer electrodeposited on the copper substrate with 25 µm grains was three times greater than that deposited on the copper substrate with 12 µm grains. After functionalization, the corrosion resistance of both films was greatly improved in both short and long immersion times in 3.5% NaCl medium.
