“…In figure 5, sample c coating has the best surface flatness, fewer defects such as micro-cracks, and difficult penetration of corrosive liquid, so its corrosion resistance is further increased. At the same time, the finer the grain size, the better the corrosion resistance [37]. However, the XRD of different coatings shown in figure 7 shows that the grain size of group d is finer than that of group c, but due to the existence of many small holes on its surface (figure 5(d)), corrosion liquid penetrates through these small holes and accelerates corrosion.…”

“…Jet electrodeposition [14][15][16], as a special form of electrodeposition, has been widely reported in the field of surface engineering in recent years. Ning et al [14] prepared Cu-carbon nanotube composite coatings with high carbon nanotube content and uniform carbon nanotube distribution by jet electrodeposition.…”

“…Ning et al [14] prepared Cu-carbon nanotube composite coatings with high carbon nanotube content and uniform carbon nanotube distribution by jet electrodeposition. Chen et al [15] studied the effects of deposition time (t), current density (i) and scanning speed (v) on the properties of Ni-Co alloy coatings prepared with 304 stainless steel as a matrix. It was found that the current density has the greatest influence on the deposition rate, microhardness and surface roughness of coating, followed by deposition time and scanning speed.…”

This study aims to address the corrosion issues faced by 45 steel to meet its usage requirements and propose a method combining liquid-phase assisted laser and jet electrodeposition. In this method, the sample surface was the first laser pretreated in different media, and then Ni was deposited on its surface using jet electrodeposition. This paper investigates in detail the effects of laser pretreatment on the surface quality of nickel coating after jet electrodeposition in four different media (Air, Water, Saturated NaHCO3, 95%C2H5OH+5%H2O2). The experimental results indicate that liquid-phase assisted laser pretreatment had improved the surface quality of Ni coating. Especially after laser pretreatment in saturated NaHCO3 medium, the adhesion of the deposited coating increased by 50% compared to air, and the roughness decreased from 20.945 μm in the air to 0.373 μm. The corrosion current density decreased from 120.2 μA·cm-2 on the substrate to 1.605 μA·cm-2.

Electrochemical 3D printing technology built on computer numerical control platforms has enabled multi-dimensional and multi-scale manufacturing of various metal materials through layered electrochemical deposition. Compared to thermal 3D printing technology, electrolyte meniscus-confined 3D printing can manufacture Cu microstructures with fewer defects and smoother surfaces. In the meantime, it is still susceptible to unstable liquid–solid-air interfaces, low deposition rates, and limited printing geometry. This work combined jet electrochemical deposition with a portable 3-axis platform to develop a cyclic high-speed electrolyte jet (HSEJ) 3D printer. It offers a faster deposition rate of 53.4 µm/h when printing ultrasmooth Cu microelectrodes with surface average roughness down to 1.1 nm and microhardness of 3.3 GPa which is much higher than the best result of 2.4 GPa obtained by the other ECD methods. It is identified that the fluctuation of cathode current density plays a crucial role in defining the nucleation morphology on the Cu surface, while the cathode current efficiency is a reliable indicator to assess the deposition localization by reflecting the variation of diffusion percentage. HSEJ 3D printing provides a sustainable pathway for the facile recycling of waste cables into high-grade metal microelectronics with controllable surface morphology and 3D dimensions.
