“…In the case of brominated fullerene the substitution of the bromine with OH groups results in derivatives with better solubility in water and in aqueous solutions [21,22]. Polyhydroxylated fullerene or fullerols (C 60 (OH) n ), have attracted much scientific and industrial attention in engineering [23][24][25], where they were found to improve the corrosion resistance and microhardness of coatings [23], to give better mechanical properties than C 60 , when incorporated in poly(styrene-co-4-vinylpyridine), in catalysis [26][27][28], for optical limiting performance [24] or to reinforce and have antioxidation effects when mixed with natural rubber to inhibit the decrease of tensile strength after aging [25]. Fullerols improve have been proposed for performing bio-oxidations [29,30].…”

The scientific and technological potential of graphene's includes the development of light, open 3D hybrid structures with high surface area, tunable pore size and aromatic functionalities. Towards this aim, we describe a scalable and low-cost bottom-up approach that combines self-assembly and Langmuir-Schaefer deposition for the production of fullerene-intercalated graphene oxide hybrids. This method uses graphene oxide (GO) nanosheets as template for the attachment of two types of fullerene derivatives (bromo-fullerenes, CBr and fullerols, C(OH)) in a bi-dimensional arrangement, allowing a layer-by-layer growth with control at nanoscale. Our film preparation approach relies on a bottom-up process that includes the formation of a hybrid organo-graphene Langmuir film, which is transferred onto a substrate and then brought in contact with C(OH) molecules in solution to induce self-assembly. In the case of grafting CBr molecules into graphene a further modification of the GO platelets was performed by bringing the surface of the transferred GO Langmuir film in contact with a second amino surfactant solution. Repeating these deposition cycles, pillared structures were fabricated in thin films form. These fullerene-based hybrid thin films were characterized by Raman and X-ray photoelectron (XPS) spectroscopies, X-ray diffraction (XRD), Atomic Force Microscopy (AFM) and contact angle measurements.

“…There are several studies reporting successful co-deposition of nickel with a carboncontaining phase, in particular, graphite [17], carbon nanotubes [18], fullerenes [19,20], and diamonds [1,[21][22][23][24][25]. Several studies report deposition of such diamond-containing composites under different conditions.…”

“…The solution is operated at elevated temperature (50-55 ºС), otherwise, it is impossible to achieve current efficiency close to 100% during deposition. The elevated temperature leads to fast evaporation of electrolyte, necessity of additional time for electrolyte heating, and control of temperature during electrolysis [25]. In our previous works [25,37,38], it was shown that replacing the buffer and complexing additive H3BO3 in nickel-plating electrolytes with organic components (acids and salts) allowed the formation of Ni coatings with desired functional and performance properties at ambient temperatures.…”

In this study, nanocrystalline Ni and Ni-diamond coatings were obtained by electrodeposition from tartrate electrolyte at ambient temperature to achieve good corrosion and wear resistance. Microhardness and adhesion tests respectively were performed for the wear resistance determination. Electrochemical impedance spectroscopy and linear polarization methods were used for corrosion resistance measurements and atomic force microscopy, and scanning electron microscopy were used for surface property characterization. The introduction of nanodiamond particles into the coating led to a rougher surface structure and a larger grain size in comparison with bare nickel coating. The study shows that the addition of 5•10 -2 (g•dm −3 ) of nanodiamonds to the plating bath is enough to obtain composite coatings with a clear increase in microhardness and wear resistance. The slightly improved corrosion resistance of the coating and decrease in corrosion current density from 0.41 to 0.14 μA•cm −2 in neutral chloride-containing medium, and nobler values of the corrosion potential were also observed.

“…The formation of Ni 3 P increases hardness and resistance to wear at the expense of formability and resistance to corrosion. [18][19][20][21] Temperature is another important factor for the properties of Ni-P electroless coatings. It was found that the reductioning agent and the complexing agent in the Ni-P electroless process is dependent on the temperature.…”

NiP -(Cu) composite coatings were applied on a St37 steel in an acidic bath of hypophosphite composite. The effect of the concentration of the Cu particles and pH of the solutionon the amount of Ni and P of the coatings, their morphology, and hardness of the coatings were explored. Some of the coated samples were also heat treated at 400ºC for 1 hour. The phases formed, the microstructure and the amount of the alloying elements of the coatings were analyzed by X-Ray powder diffraction (XRD), Scanning Electron Microscope (SEM) equiped with Energy Dispersive Spectroscopy (EDS). Results show that although adding Cu particles reduced the hardness of NiP coating (from 482.4 to 351.2 VH in 1 gr/lit Cu), within NiP -Cu composite coatings the hardness of NiP -Cu composite coating increased from 351.2 to 380.7 VH by increasing the Cu particles from 1 to 7 gr/lit. The structure of the coating was crystalline during the heat treatment making the coating harder. With increasing the pH of the solution from 4.5 to 7 and then to 9, the weight percent of P and the particle of Cu were reduced.
