“…Imanian et al performed experiments along the lines of Ni-based electrodeposition coating. They ascertained that the micro hardness, corrosion, and wear resistance properties ameliorated along the coated regions, but was susceptible to delamination with surge in wear [7]. Ataee et al consummated a study on pre-eminence of SiC nanosized particles on the arrangement along with the attributes through electrodeposited Fe/SiC nanosized composite coating.…”

“…To obtain nano structured coatings electro deposition is generally preferred over physical vapour deposition (PVD), chemical vapour deposition (CVD) and sputter-coating techniques [14][15][16] as it involves low temperatures, economically viable to operate and the thickness of coating can be controlled to the precise amount based on the required micron levels (thickness being a variable factor) by varying the parameters. In electrodeposition or electroplating, the process of material deposition happens with a solution containing ionic species (salts) onto a conducting surface [5][6][7]. This technique is commonly used to coat thin film materials on the object surface to change the properties by means of increasing corrosion resistance, improving abrasion resistance by surge in the hardness and wear resistance factors.…”

Nano composite coatings on HSLA ASTM A860 alloy, adds to the barrier efficacy by increase in the microhardness, wear and corrosion resistance of the substrate material. Additionally, reduction of delamination of the nano composite coating sample is ascertained. Ball milling is availed to curtail the coating samples (Al2O3/ZrO2) to nano size, for forming a electrodeposited product on the substrate layer. The curtailment in grain size was ascertained to be 17.62% in Ni-Al2O3/ZrO2 nano composite coating. During the deposition process, due to the presence of Al2O3/ZrO2 nano particles an increase in cathode efficiency is ascertained. An XRD analysis of the nano composite coating indicates a curtailment in grain size along with increase in the nucleation sites causing a surge in the growth of nano coating layer. In correlation to uncoated HSLA ASTM A36 alloy sample, a surge in compressive residual stress by 47.14%, reduction of waviness by 32.14% (AFM analysis), upsurge in microhardness by 67.77% is ascertained in Ni-Al2O3/ZrO2 nano composite coating. Furthermore, in nano coated Ni-Al2O3/ZrO2 composite a reduction is observed pertaining to weight loss and friction coefficients by 27.44% and 13% in correlation to plain uncoated alloy respectively. A morphology analysis after nano coating indicates, Ni-Al2O3/ZrO2 particles occupy the areas of micro holes, reducing the wide gaps and crevice points inside the matrix of the substrate, enacting as a physical barrier to upsurge the corrosion resistance by 67.72% in correlation to HSLA ASTM A860 base alloy.

“…In this regard, electrodeposition is very attractive in comparison with other methods due to its simplicity, ease of control, minimal required material preparation, and relatively cheap equipment [9]. In the electrodeposition process, metal ions from anodes preferably nucleate and grow on the lattice defects of cathode surface [18,22] where the screw-dislocation-driven growth mechanism is dominant for 2D and 3D growth during electrocrystallization [23,24]. With the gradual increase of supersaturation in the system, the crystal-growth mode progressively changes from screw-dislocation-to layer-by-layer-and then to dendritic-growth mechanisms [18,23,25].…”

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.

Herein, the effect of WC content (ranging from 0 to 12 g L−1 in the bath) is studied on the corrosion and wear properties of the Ni–W–B/WC pulse‐plated composite coatings. Results display that at the first step, increasing WC concentrations in the bath (up to 4 g L−1) increases WC content in the coating. However, further addition of WC particles decreases WC content in the coating because of the agglomeration of nanoparticles. Furthermore, the corrosion and wear resistance of the deposits improve considerably with raising the WC amount in the deposits. In other words, the coating electroplated at 4 g L−1 of nanoparticles in the bath displays the best electrochemical and wear behaviors. The uniform distribution of reinforced particles in the deposit is the main reason for achieving superior properties. A maximum corrosion resistance of about 65.8 kΩ cm2 is attained in the coating with 4 g L−1 WC in the bath. In addition, this coating displayed minimum values of wear weight loss (0.288 mg cm−2) and the friction coefficient (0.348). Higher WC contents in the bath negatively affect the properties of the coatings because of the existence of agglomerated particles and decreasing nanoparticle amounts in the coatings.
