“…These barriers inhibit corrosion processes from spreading in the sample. Grain boundaries in polycrystalline Cu-Ni-W thin films are interfaces between adjacent grains [75]. Additionally, the presence of (111) texture as confirmed by X-ray diffraction measurements is attributed to the more corrosion-resistant characteristics of the films.…”

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.

“…Once local damage occurs, it needs to be replaced as a whole, and the replacement cycle is long. Therefore, to extend copper service life and improve its wear resistance, corrosion resistance, and other properties, many scholars at home and abroad have analyzed the damage to copper alloy components [5][6][7]. Commonly used repair technologies for copper alloys include surfacing technology, laser cladding technology, and cold spray technology [8,9].…”

Plasma‐assisted low‐pressure cold spraying and conventional cold spraying methods are used to prepare copper coatings on copper substrates. The thickness, porosity micromorphology, and mechanical and corrosion properties of the copper coating prepared by high‐pressure cold spraying and plasma‐assisted low‐pressure cold spraying are studied. The results indicated that in single‐pass deposition, the copper coating prepared by plasma‐assisted low‐pressure cold spraying has a small porosity and a thick coating under the spraying conditions with the same powder feeding rate, which has a better deposition effect. The coating grains prepared by the plasma‐assisted method undergo a recrystallization process, and the grains are refined. Plasma‐assisted low‐pressure cold spray technology can achieve a good repair effect on parts.

Nanocrystalline nickel–cobalt (Ni–Co) binary alloy sheets were fabricated through electroforming in an acidic aqueous bath using exfoliation from a metallic titanium cathode. Cobalt content in Ni–Co alloy sheets ranged from 28.8 at% to 72.0 at% depending on experimental parameters, such as cathodic overpotential and bath composition. The surface roughness (Ra) of the electroformed alloy sheets significantly decreased down to 1.5 μm as saccharin sodium dihydrate was added as an additive to the acidic aqueous solution bath. X-ray diffraction profiles and transmission electron microscopy images indicated that the electroformed Ni–Co alloy sheets have a nanocrystalline structure (grain size ≈ 30 nm). The lattice constant of the electroformed Ni–Co alloy sheets increased with an increase in cobalt content (i.e. solute atom concentration). The mechanical properties were significantly improved because of the synergistic effects of crystal grain refinement and solid solution strengthening. The microhardness and tensile strength of the electroformed Ni–Co alloy sheets reached 609 kgf/mm2 and 1757 MPa (XCo = 49.9 at%), respectively. The tensile strength of the electroformed Ni–Co alloy sheets in this study significantly exceeded that of solidified Ni–Co alloys (approximately 370 MPa). Therefore, this study offers a technique to enhance the mechanical properties of electroformed Ni–Co alloy sheets.
