“…There is disagreement in the modern literature as to whether a material with a broad diffuse diffraction peak should be called X-ray amorphous 26 or nanocrystalline. 27 In addition, it has been suggested that for electrolytic alloys of refractory metals, the simultaneous existence of intermetallic and solid solution phases is possible. Moreover, one of these phases can be nanocrystalline, and the other amorphous.…”

“…Moreover, one of these phases can be nanocrystalline, and the other amorphous. This conclusion 27 was made on the basis of the calculated parameters of the unit cell. From the size of the broad peak, which in terms of the diffraction angle corresponds to a solid solution of rhenium in cobalt, as well as the formation of the intermetallic compound Co 0.8 Re 0.2 , one can approximately estimate the crystallite size of 2-3 nm.…”

“…The formation of specific crystallographic orientation of Cu-Ni-W thin films structure implies that the crystal lattice is aligned in a particular direction, which can affect the properties of the materials. The conclusion that can Cu-Ni-W alloy is nanocrystalline in nature is based on the observation of broad diffraction peaks and the small grain size estimated by the diffraction pattern [64]. Debye Scherrer formula is used to estimate the crystallite size of (111), ( 200) and (220) crystallographic plane.…”

Cu-Ni-W thin films are deposited by varying the current density from − 5 to -60 mA/cm² using the galvanostatic chronopotentiogram method on ITO-coated glass substrates. The X-ray diffraction (XRD) analysis revealed that Cu-Ni-W thin films exhibit a face-centered cubic structure with the presence of specific crystallographic planes, particularly (111), (200), and (220), at 2θ values of 43.4°, 50.7°, and 74.7°. The additional peaks observed at other 2θ values correspond to NiW and Ni4W phases. It is found that film deposited at higher current densities favor the growth of smaller crystalline size of 17 nm and higher degree of texture coefficient of 2.48. The maximum value of micro-strain of about 16% is calculated from the peak broadening of X-ray diffractograms. Due to the strong (111) texture and nano crystallites as confirmed by XRD resulted in an outstanding corrosion resistance of 16.22 kΩ cm² for the film deposited at -60 mA/cm².

“…Usually, in a harsh environment, such as marine medium, it is essential to research more advanced coatings with an excellent integrated performance of corrosion resistance and wear resistance. Among many surface coating techniques, electrodeposition is one of the most widely used methods to enhance the surface protective properties, especially anti-corrosion and wear-resisting properties [2,3], which is simple, efficient and inexpensive [4].…”

In this work, the structure and properties of ZrO2 nanoparticle reinforced Ni–W, Ni–B and Ni–Cu matrix nanocomposite coatings were comparatively studied. Their surface morphology, composition, microstructure, topography, hardness, wear and corrosion resistance were examined by various methods . The nanocomposites exhibit dense, nodular-like morphology with nanocrystalline structure. The results show that the ZrO2 particles have homogeneously dispersed in the nanocomposites. The formation of the protrusion structure was partly attributed to the heterogeneous distribution of the electric field. The presence of ZrO2 nanoparticles could refine the crystallite size of the Ni–W, Ni–B and Ni–Cu alloy matrix to 12.5 ± 1, 10.5 ± 0.5 and 15 ± 0.1 nm, respectively. The corrosion resistance of these nanocomposites can be improved by the incorporation of ZrO2 nanoparticles into the alloy matrix. The R a of Ni–W/ZrO2, Ni–B/ZrO2 and Ni–Cu/ZrO2 nanocomposites are about 53 ± 3, 69 ± 2, 18 ± 1 nm, respectively, expressing the rougher surface of Ni–B/ZrO2 compared to the others. It indicated that the composition of these alloy matrix have different crystallite size, which could affect the surface roughness of the electrodeposits. The inclusion of ZrO2 particles in Ni-based alloys could enhance its properties. The reinforcement effect of the anti-wear properties of the nanocomposites was proposed. The R ct value of the Ni–W–ZrO2, Ni–B–ZrO2, Ni–Cu–ZrO2 were 50.93, 105.18, 44.67 kΩ · cm2, respectively, indicating that the Ni–B–ZrO2 nanocomposite coating has the highest corrosion resistance. The R ct values depends on not only the composition of the coatings, but also the electrodeposition conditions, which influence the crystallize size and compactness of the electrodeposits. The order of the microhardness and anti-wear properties is Ni–W–ZrO2 > Ni–B–ZrO2 > Ni–Cu–ZrO2.
