In order to achieve the optimum conditions for electroplating nanocrystalline nickel coating from Watts-type bath, the effect of some process parameters namely, bath temperature, current density, and saccharin addition on grain size and texture coefficient (TC= I₍₂₀₀₎/I₍₁₁₁₎) of the deposits were investigated by X-ray diffraction (XRD). The results showed that in a bath containing 5 g/L saccharin, by increasing the bath temperature from 45°C to 55°C, the grain size decreased, whereas further increase of bath temperature resulted in a contrary effect. By increasing the current density from 10 to 75 mA/cm², both the grain size and TC decreased, while further increase in current density had no significant effect on the grain size. At a given current density, the grain size and TC decreased rapidly by increasing the saccharin content before leveling off at 3 g/L of saccharin. Finally, based on the grain refining the optimum conditions for producing nanocrystalline nickel coating from Watts-type bath have been proposed.

Exploring the potential of nickel-chloride bath for electroforming of pure nickel and nickel composites
2024, Materials Chemistry and Physics
Electroforming is becoming increasingly important as a reliable method for the production and replication of independent parts. Researchers are continually striving to reduce production costs for the fabrication of complex tools with the highest precision and lowest cost, and electroforming is a key technique for achieving this goal. The present research aimed to produce pure nickel foils via electroforming using a simple and inexpensive nickel-chloride bath, which has not been previously utilized for electroforming. The effects of saccharin concentration, nickel-chloride concentration, direct current density, and the use of graphite as an insoluble anode were investigated. The surface morphology of the electroformed products was characterized through scanning electron microscopy (SEM) and their chemical composition was analyzed using energy dispersive x-ray (EDX) and x-ray diffraction (XRD) pattern. The microhardness of the foils was determined using the Vickers hardness test. Results showed that specimens produced using the nickel-chloride bath had a good surface appearance with acceptable brightness and satisfactory microhardness. Ten electroforming tests were conducted to determine the optimal bath components, pH, and direct current density for the fabrication of pure nickel products. It was found that these parameters had a significant influence on the quality of the appearance and surface morphology of the foils. In addition, using a graphite anode was seen to reduce the cathode current efficiency as compared to a soluble nickel anode and was affected by the preferred orientation of nickel crystal plates. It can be concluded that the nickel-chloride bath has excellent potential for the production of pure nickel products using the electroforming method.
Chemical and bio-mediated processes for the synthesis of nanomaterials
2024, Nanomaterials in Biomass Conversion: Advances and Applications for Bioenergy, Biofuels, and Bio-based Products
Nanomaterials are the emerging class of materials that have a broad spectrum of applications in diverse fields. At the nanoscale, materials possess outstanding magnetic, electrical, mechanical, optical, and catalytic properties than their bulk counterpart. To produce the nanomaterials with desired properties, size, shape, and high surface area, the synthesis method plays a key role. There are many methods widely used for the synthesis of nanomaterials. In this chapter, we will mainly focus on the chemical and biological routes of the synthesis of nanomaterials. In particular, we will describe all the recently used chemical (co-precipitation, hydrothermal, aqueous chemical growth, sol–gel, sonochemical) and biological (plant extract, bacterial, algae, etc.) methods for the synthesis of nanomaterials in detail. Finally, we will conclude our discussion with the challenges and future perspectives regarding the synthesis of nanomaterials.
Evaluation of Ni–B alloy electroplated with different anionic groups
2023, Journal of Materials Research and Technology
In order to study the effects of the main nickel salt on the electroplated nanocrystalline Ni–B alloy coating, the deposition rates, surface morphology, crystallinity, grain sizes, hardness, and corrosion resistance of the Ni–B films electrodeposited with plating baths containing separately nickel sulfate (NS) and nickel sulfamate (NSA) under various temperatures and current densities were compared. Under all conditions, the NSA bath system offered higher deposition rates and lower B contents than the NS counterpart because of the formation of Ni-ammonium complex, which can be adsorbed faster than nickel ions. These two groups of coatings had similar surface morphology and crystallinity under all plating conditions except for those plated with the NS bath system at 60 °C, wherein significant changes in surface texture and preferred crystal orientation as well as an abrupt increase in grain size occurred. The coating hardness was optimized by reducing the grain size and increasing the boron content because of the combined effects of grain refinement strengthening and solid solution strengthening. The differences between the two main salt systems can be explained by the presence of ammonium ions in the NSA bath, which not only increased the deposition rate but also maintained the preferred orientation in Ni (111) at high temperature. Our results indicate that, under high current density and high temperature operation conditions, the NSA main salt plating system is a more favorable option for obtaining higher quality Ni–B alloy coatings.
Effect of polyethylene glycol molecular weight on the electrodeposition of nanostructured nickel
2023, Applied Surface Science
Electrodeposition is an attractive approach to synthesize nanostructured metals and their microstructure can be effectively controlled by tuning the process parameters. Here, two molecular weight (MW) types of polyethylene glycol (PEG) were used as additives for nickel electrodeposition in Watts bath. The surface morphology, crystal orientation, microstructure and microhardness of the Ni film were investigated. Experimental results revealed that the MW of PEG played a decisive role in controlling the microstructure of the deposits. As the current density increased from 25 to 100 mA/cm², the microstructure of the Ni film deposited from the PEG₆₀₀-containing bath evolved from ultrafine grains with nanotwin lamella perpendicular to the substrate surface to randomly oriented nanotwins, where the average grain size decreased from 118 nm to 78 nm. Within the same current density range, the Ni film obtained from the PEG₁₀₀₀₀-containing bath presented fine nanograins with multifold nanotwins (e.g., fivefold nanotwins) in random orientations with the average grain sizes of around 10 nm, little influenced by the current density. Such microstructure transition could be attributed to that the addition of PEG facilitated the formation of twins, and higher MW PEG induced a greater inhibition effect, promoting significant grain refinement.
Construction and anti-corrosion behavior study of silanol-modified Ni-WS<inf>2</inf> superhydrophobic composite coating
2022, Surface and Coatings Technology
In this study, a novel superhydrophobic composite coating is prepared by a two-step method. Firstly, the Ni-based deposition coating is fabricated via composite electrodeposition with WS₂ granules worked as dispersed phase particles, and the roughness of deposit coating can be adjusted by changing the added amount of sulfide in the bath. The prepared Ni-WS₂ deposit exhibits sufficiently high roughness and suitable micro-nano morphology. Then, hexadecyltrimethoxysilane (HDTMS) is used to modify the deposition coating with low surface energy to obtain silanol-modified Ni-WS₂ coating with superhydrophobic properties. The superhydrophobic behavior of the composite coating conforms to the Cassie-Baxter model, with low adhesion to aqueous solutions. When the addition amount of WS₂ particles in the plating solution during the electrodeposition process is 5 g·L⁻¹, the prepared composite coating has the excellent superhydrophobic properties. The water contact angle of the composite coating is 154.7° ± 2 and the sliding angle can reach 6°. And the superhydrophobic composite coating exhibits excellent corrosion resistance.
Pulsed electro-synthesized tunable crystallite sizes ZnMn<inf>2</inf>O<inf>4</inf>/Mn<inf>2</inf>O<inf>3</inf> nanocomposite as high-performance cathode material for aqueous zinc-ion batteries
2022, Journal of Alloys and Compounds
Rechargeable aqueous zinc ion batteries (ZIBs) are one of the most promising candidates for large-scale energy storage, due to their high capacity, high hydrogen evolution potential, safe and cost-effective components while benefiting from the abundance of active materials. However, ZIBs still suffer from suitable cathode materials with high capacity and superior cycling stability. Herein, we study a new strategy for the synthesis of tunable crystallite sizes ZnMn₂O₄/Mn₂O₃ nanocomposite using the pulsed potential method. The effect of synthesis potential on structural, morphological, and electrochemical properties of nanocomposite was investigated via different characterization techniques. According to our results, the functional and electrochemical properties of ZnMn₂O₄/Mn₂O₃ nanocomposite are profoundly affected by the synthesis potential. The crystallite sizes of synthesized nanocomposites can be tuned from 20.2 nm to 29.3 nm, depending on the applied potential. However, the exposed surface area of nanomaterials is ranged between 50.3 m² g⁻¹ and 132.0 m² g⁻¹. The developed nanocomposite was investigated as the cathode material for aqueous zinc ion batteries. The ZnMn₂O₄/Mn₂O₃ nanocomposite exhibited an excellent discharge capacity of 216.8 mAh g⁻¹ at 0.2 A g⁻¹ after 200 cycles. In addition, the developed cathode showed to preserve 97.8% of its initial capacity for 2000 cycles at 2 A g⁻¹. Apart from the high specific capacity and long cycle stability, the facile synthesis method can offer the ZnMn₂O₄/Mn₂O₃ nanocomposite as a high-performance cathode material for durable zinc ion batteries.
