“…The hardness measurement result is seen in Figure 7. Hardness seems linearly within crystallite size, aligning with the previous research [20]. Increasing crystallite size would decrease hardness and vice versa [21][22].…”

A spinning magnet is an alternative engineering approach to produce the Ni layer. In the present research, the Ni layer was plated on Cu alloy substrates influenced by a spinning magnet. Various rotating speeds (0, 500, and 800 rpm) were used to influence the Ni layer’s properties were formed. A digital scale was used to measure the deposition rate and cathodic current efficiency. XRD, SEM-EDS, potentiostat, and hardness tests were performed to determine the properties of the Ni layers. A rotating magnetic field can reduce the deposition rate and cathodic current efficiency by reducing the ionic movement from the anode to the cathode. The XRD and SEM results revealed a distinct crystallite size and surface morphology. Exhibiting a spinning could result in a decrease in oxygen in the Ni layer and a slight change in the corrosion rates. Different hardness is also seen in the various sample due to crystallite size.

This article presents a study on influence of Copper Concentration Electrolyte (CCE) and voltage on deposition rate of electroformed Conductive Acrylonitrile Butadiene Styrene (CABS) produced through Fused Deposition Modeling. Additive manufacturing is widely recognized as a rapid production technology. In this research, copper electroforming was selected as subsequent treatment following additive manufacturing. The novelty lies in implementation of pre-treatment process involving electroforming. The pre-treatment process employs carbon conductive paint to render the ABS part conductive. The copper electroforming process involves the use of variable parameters such as electrolyte content of (100, 150, and 200 gram CuSO4 and 50 ml H2SO4) in 1 liter H2O, voltage (1, 2, and 3 Volts), and time (2, 4, 6 and 8 hours). The variables under observation include the copper deposition rate and the microstructure. The analysis of research based on Kruskal-Wallis test. The difference in electrolyte copper concentration and the coating time does not provide significant differences, while the duration of electroforming affects the thickness of the copper deposit. Furthermore, the concentration of copper electrolyte influences the solution's conductivity, at high concentrations leading to improve conductivity and consequently facilitating a fast deposition rate. The difference in voltage has a significant effect on the deposition rate and microstructure.

“…In the pulse current state, less nano particles agglomerated, and caused more uniform dispersion of nano particles [39]. The metal foam structure does not in itself have a high surface area; thus, in catalyst applications, deposition of a high surface area coat e.g., Al2O3(γ), SiO2, or zeolite by wash-coating, solgel, electrochemical deposition, electrophoretic, chemical vapor deposition (CVD) or physical vapor deposition (PVD) is necessary [9,40,41].…”

Global warming persuades researchers to improve the effectiveness of renewable energy technologies, such as H2 production by methane steam reforming (MSR) an endothermic process. Herein, a nanocatalyst based on open-cell nickel foam 40 (pore per inch) with high thermal conductivity was prepared. The nanocatalyst was synthesized with a chemical stepwise synthesis approach, chemical pretreatment, pulsed electrocodeposition of Ni-Al2O3(γ) nanoparticles, and calcination. Measurements of thermal diffusivity(α) with flash xenon technique gained 4.41×10 -6 m 2 s -1 and values of specific heat capacity, Cp, by differential scanning calorimetry (DSC) and thermal conductivity(λ) enhanced by 65% in temperature range of 150 to 550°C in Ni-alumina(γ) foam nanocatalyst. Furthermore, characterization and tests for comparing nickel foam and Ni-alumina(γ) foam indicated that the hardness improved from 145 Vickers hardness (HV) to 547 HV and compression strength increased from 1.1 MPa to 5MPa and specific surface area (SBET) from 1.48 m 2 g -1 to 48 m 2 g -1 . XRD (x-ray diffraction) analysis showed NiO and NiAl2O4 in the structure. The interface between the catalytic component (NiAl2O4), and nickel affected the catalytic ability for MSR, and the efficiency gained at low tempreture 500 °C was the same as reported at 720°C by other investigations.
