“…To date, many physical and chemical growth techniques have been developed that are utilized in the production process of magnetic thin film samples. Among the growth techniques developed, the electrochemical deposition technique has been successfully used in computer read/write heads and Micro-ElectroMechanical Systems (MEMS) applications due to its unique features [1,3,[6][7][8][9][10][11][12]. It is well known that ternary ferromagnetic alloy films are interesting soft magnetic materials due to their high saturation magnetization and low coercive field [4,6].…”

In this study, to explore the effect of Co contents on the electroplated Fe–Co–Ni samples, three different Fe–Co33–Ni62, Fe–Co43–Ni53, and Fe–Co61–Ni36 samples were electrochemically grown from Plating Solutions (PSs) containing different amounts of Co ions on indium tin oxide substrates. Compositional analysis showed that an increase in the Co ion concentration in the PS gives rise to an increment in the weight fraction of Co in the sample. In all samples, the co–deposition characteristic was described as anomalous. The samples exhibited a predominant reflection from the (111) plane of the face–centered cubic structure. However, the Fe–Co61–Ni36 sample also had a weak reflection from the (100) plane of the hexagonal close–packed structure of Co. An enhancement in the Co contents caused a strong decrement in the crystallinity, resulting in a decrease in the size of the crystallites. The Fe–Co33–Ni62 sample exhibited a more compact surface structure comprising only cauliflower–like agglomerates, while the Fe–Co43–Ni53 and Fe–Co61–Ni36 samples had a surface structure consisting of both pyramidal particles and cauliflower–like agglomerates. The results also revealed that different Co contents play an important role in the surface roughness parameters. From the magnetic analysis of the samples, it was understood that the Fe–Co61–Ni36 sample has a higher coercive field and magnetic squareness ratio than the Fe–Co43–Ni53 and Fe–Co33–Ni62 samples. The differences observed in the magnetic characteristics of the samples were attributed to the changes revealed in their phase structure and surface roughness parameters. The obtained results are the basis for the fabrication of future magnetic devices.

Based on the above-mentioned discussion, a highly stable electrode could be fabricated by electrodepositing a bimetallic CuNi alloy (where Cu can electrodeposit easily and allow codeposition of highly OER-active Ni), and the insertion of a nonmetal such as P could shift the electron density from the metal to P and modify the electronic structure of the electrode and improve the ability of charge transfer to promote the OER.…”

Development of low-cost and highly abundant transition metal-based electrocatalysts for oxygen evolution reaction (OER) activity with low overpotential and high stability is desired for the utilization of electrolytic water-splitting cells to generate hydrogen (H2) fuel. The electrocatalytic activity could be further improved with the fabricated catalyst possessing microporous structures. In this study, binder-free hydrogen bubble-assisted electrodeposition of Cu, Ni, and phosphorous over a Cu sheet (CuNiP@Cu sheet) electrode was constructed. Three electrodeposition solutions consisting of 3:1, 1:1, and 1:3 mole ratios of Cu to Ni and 0.50 M sodium hypophosphite were utilized to produce electrodes under a range of electrodeposition potentials from −2.0 to −9.0 V vs Hg/Hg2SO4 so as to control the rate of hydrogen bubble template generation. The optimum performance for the OER in 1.0 M KOH solution was achieved using the electrode [i.e., CuNiP@Cu (1:1)] generated from an electrodeposition solution consisting of 1:1 mole ratio of Cu to Ni at −4.0 V vs Hg/Hg2SO4 for 5–20 min, which demonstrated a low overpotential value of 318 mV to achieve 10 mA/cm2 current density with a Tafel slope of 100 mV/dec. The potentiodynamic studies of the electrode showed minimal change in the overpotential value for the OER even after 786 cycles at a scan rate of 200 mV/s. The stability was also confirmed with the potentiostatic studies in which the electrode was found to be stable for 20 h of the experimental time. The outcomes suggest that low-cost, readily synthesized, and binder-free hydrogen bubble-assisted one-step electrodeposited microporous electrocatalysts hold excellent features toward the OER.

Pool boiling heat transfer (BHT) of R-141b on porous Cu coated heating surface was experimentally studied. Porous Cu coating was fabricated on a plain Cu heating surface through a two-stage electrodeposition method. Surface characterization of Cu coating confirmed the successful synthesis of micro/nano-porous Cu coating. Experimental results showed that the Cu coated heating surface introduced a significant enhancement in heat transfer coefficient (HTC) and a great reduction in wall superheat compared to the plain Cu surface. The maximum enhancement in HTC for the Cu coated heating surface was approximately 53% compared to the uncoated heating surface. This is believed to have resulted from the increase in active surface area, nucleation site density and cavitation activity owing to the microporous structure of Cu coating. Obtained results showed that the microporous Cu coated heating surface could be employed in modern heat transfer applications.
