“…Table 4, summarizes the electrochemical data calculated from anodic and cathodic slopes using the Tafel extrapolation method. The corrosion resistance (Rp) is found to be 16.22 kΩ cm² which is higher as compared to the previous studies on similar systems [50][51][52]74]. The value of Icorr is observed in the range of 2.60 -3.10 µA/cm².…”

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.

“…Such direct interaction would result in the formation of a non-soluble nickel tungstate compound in the electrodeposition bath [31,32]. Sodium saccharin was used to decrease the internal stress within the coating [33]. We used propargyl-oxo-propane-2 and 3-dihydroxy as a brightener and grain refiner to control the Ni ion diffusion towards the cathode.…”

Compact and uniform NiW composite coatings filled with ceramic particles such as CeO2 were electrodeposited on brass substrates using direct current (DC) and a well–designed pulse reverse current waveforms (PRC). PRC coatings exhibited the noblest corrosion potential and lowest current density compared to DC–electrodeposited coatings. Among all PRC coatings, PRC–NiW–CeO2 demonstrated the highest corrosion potential (−4.72 × 10−1 V) and the lowest current density (5.32 × 10−6 V). It also seems that the addition of CeO2 particles to the NiW matrix enhanced the wear resistance of the coatings, and the lowest wear volume of (133.10 × 103 µm3) and friction coefficient of 0.25 were obtained due to the formation of the uniform, void free and compact structures with a high content of CeO2 particles in the coating.

The precise control of tungsten content of electrodeposited nickel-tungsten (NiW) on brass substrate was achieved by applying a well-designed pulse reverse current waveform. A crack-free, uniform and, mirror-like finish surface was obtained by using a novel derivative of propargyl compound, propargyl-oxo-propane-2,3-dihydroxy, as a brightener and grain refiner into the electrodeposition bath. This study indicates that the electrodeposited nickel-tungsten alloys with an optimum tungsten content (32 wt%) possesses outstanding mechanical and, wear performance, also with very low friction of coefficient of 0.2.
