“…In the work [3], Ni-B/GO composite alloy coatings were the starting point for the production of superhydrophobic coatings for the corrosion protection of AZ91 magnesium alloy. Gul et al [4] found improved corrosion resistance and tribological properties of ternary Ni-B-P alloy coatings with embedded carbon nanotubes. Better corrosion resistance and improvement in mechanical properties of nickel-boron coatings can be achieved by incorporating α-ZrP particles [5].…”

Composite coatings have been successfully fabricated at the laboratory scale in many research centers around the world; however, it is still a major challenge to transfer the positive results of the work to the industrial scale. This paper presents the technology for the production of Ni-B and Ni-B/B composite coatings on a pilot experimental semi-technical line by chemical reduction. A process scheme for the fabrication of Ni-B layers and composite coatings with a nickel–boron matrix and a dispersive phase in the form of boron nanoparticles was developed. All stages of the fabrication process were described in detail. The dispersion phase of the boron particles was characterized, and the performance properties of the Ni-B and Ni-B/B composite coatings produced on a pilot electroplating line were studied. The structure and morphology of the Ni-B/B composite coatings were characterized for comparison with nickel–boron coatings. Their mechanical and tribological properties and adhesion to the substrate were studied. The influence of the dispersion phase of boron particles on the structure and functional properties of the composite coatings was evaluated. In order to improve the performance of the fabricated coatings, a heating process at 400 °C was carried out, and the performance of Ni-B and composite Ni-B/B coatings was studied after the heat treatment operation.

“…Based on the application, the weight percentage of P is varied; decorative purpose coatings contain 4–7% of P, industrial purpose coatings contain 6–9% of P, and electronic applications contain 4–10% of P. High phosphorus coatings contain a phosphorus weight percentage greater than 10.5% and offer higher resistance to corrosion. These types of coatings are used in highly corrosive acidic environments, such as oil drilling and coal mining [ 8 , 9 , 10 , 11 , 12 , 13 ].…”

“…Ni-B coatings are another essential kind of nickel alloy coatings, where borohydride is considered as a reducing agent. As compared with the Ni-P coatings, nickel–boron (Ni-B) coatings show high hardness, wear resistance, and low corrosion resistance [ 13 , 14 ]. The boron concentration greatly influences the structural and mechanical properties of the coatings.…”

Nickel-Phosphate/Boron (Ni-P/B) electroless coatings have been widely used to improve physical and mechanical properties in various industrial applications, including the automotive, aerospace, chemical processing, food, oil and gas, electronic, textile, and printing industries. Electroless nickel coatings are one of the most popular surface-coating methods due to their low cost and short processing time. The purpose of this review is to look at several coating materials and the existing processes for making electroless coatings on different materials. The improvement of Ni-P/B composite coatings by the incorporation of secondary particles into an alloy matrix at the macro, micro, and nano levels is explained in detail. Process parameters like type of surfactant, annealing temperature, size of the reinforcement material, and reducing-agent percentage on mechanical characteristics like hardness, high-temperature oxidation behaviour, friction, coefficient, wear, and corrosion have been broadly researched and illustrated clearly.

“…Ni-based electroless coatings, namely Ni-P and Ni-B, have been extensively studied in recent years due to their useful properties for industry. Ni-P coatings have relatively high hardness, good solderability, and are resistant to corrosion, while Ni-B coatings are well-known for their excellent mechanical characteristics, such as their high resistance to wear and surface stress, which exceed even those of hard chromium coatings [1][2][3][4][5][6][7].…”

Amorphous electroless Ni-B coatings were deposited on steel substrates with different surface morphologies and B contents (6.5–8.64 wt.%) that could be changed by altering the temperature and the composition of the baths. The supercapacitive behavior of the coatings was evaluated by cyclic voltammetry and galvanostatic charge–discharge measurements, and it was found that Ni-B coatings had higher capacitance than pure electroless Ni or the bulk Ni plate. A close relationship was identified between the microstructure, the B content, and the capacitive behavior of the coatings. The presence of the B alloying element had the most significant effect in determining the capacitance, while the surface area and particle size also contributed to its increase. A surface-specific capacity of 31 mF/cm2 was achieved by the coating containing the highest B content and largest AFM surface area. Furthermore, it was revealed that the particle size of the deposits was determined by the combined effect of the bath temperature and the B content under the applied experimental conditions. The obtained results indicate that Ni-B coatings are promising candidates for supercapacitive applications.
