Summary: The research discovered that applying pulse electrodeposition with a triangular waveform to Ni-Cu alloy coatings resulted in the best corrosion resistance, while using a ramp waveform led to the lowest surface roughness and grain size. Additionally, the corrosion resistance of the Ni-Cu alloy coatings was found to depend significantly on the molar fraction of Cu in solid solution and the crystallographic orientation, with the highest corrosion resistance associated with the largest molar fraction of Cu in solid solution and growth of grains at (111) orientation.

Summary: Based on previous research, the addition of Ti3C2TX in Ni-W-Ti3C2TX composite coating improves its hardness by 24.3% compared to Ni-W alloy coating without Ti3C2TX. Additionally, the wear resistance and corrosion resistance of the composite coating are significantly enhanced. The study investigates the influence of bath pH on the coating's morphology, composition, mechanical properties, corrosion resistance, and friction resistance. It is found that the surface morphology of the coating improves as the pH value increases. The suitable pH value of 9 provides the best corrosion resistance and tribological properties for the composite coating.

Summary: Single-layer and multilayer alloy deposits were electroplated onto a mild steel substrate, consisting of Zn and Fe alloys with different compositions. The corrosion resistance of these deposits was evaluated using potentiodynamic polarization method, while their surface morphology, crystal structure, and Fe content were characterized using scanning electron microscopy, X-ray diffraction, colorimetry, and energy-dispersive X-ray spectroscopy, respectively. The microhardness of the coatings was measured using a Vickers indenter. It was found that the Zn-Fe multilayer coatings showed significantly improved corrosion resistance compared to the single-layer coating, making them crucial for the automotive industry and steel-based vehicle parts.

Summary: This paper focuses on the electrodeposition of nanocrystalline Ni-W-Co ternary alloy film on copper substrate. The effects of electrodeposition parameters on the structural, compositional, surface characteristics, and corrosion properties of the alloy were investigated. It was found that the alloy has a uniform, compact, and flat surface with colony-like morphology. The crystalline structure and surface roughness are greatly influenced by the current density, bath pH, and plating time. Co content has little effect on crystallite size. The composition of the alloy shows a decrease in nickel content and an increase in Co content. The optimized process parameters for corrosion and wear resistance were determined.

Summary: This study developed a strategic approach to improve the device performances of CZTSSe solar cells by combining back-interface passivation and doping. The passivation of the back interface and the doping of a germanium nanolayer improved the grain growth, reduced the thickness of harmful layers, improved the absorber bulk quality, suppressed defects, and reduced nonradiative carrier recombination losses. As a result, the short-circuit current density, fill factor, and power conversion efficiency of the devices significantly increased.
