“…The current methods for preparing nickel coating mainly include chemical plating [5], vapor deposition [6], laser-assisted [7,8], and electrodeposition [9]. The process of chemical plating is simple and does not require electricity, but its disadvantage is that the coating thickness is large, and the uniformity is poor [10]. The film thickness control accuracy of vapor deposition is high with a good film quality and the uniformity is good.…”

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.

“…With excellent toughness and ductility, promoted hardness, and good bonding with diamond particles [17,18,[22][23][24], nickel is suitable as the co-depositing metal matrix with micro-diamond particles to process hard and brittle RG. The thermal stability of nickel-diamond composite coating is also significantly enhanced [25,26] and becomes a minor issue during a welllubricated and fine milling process, which can be evaluated by its thermal properties, like glass transition temperature (Tg) and the onset of the crystallization (Tx) [27,28]. In this paper, a new type of microdiamond coating for milling tool was proposed.…”

Currently thin-plate glass used in portable devices is initially segmented by laser beam. The material melts and vaporizes during the process, which requires micro-tools for further edge milling. Due to the poor wear resistance and short life of the micro-milling tools and the fragile nature of the glass, the processing cost is high due to the low yield. In this study, a new alternative for preparing micron diamond milling tools was reported. Bilayers on brass substrates by a composite electrodeposition technique was prepared by using diamonds with a diameter of 2-4 μm. In order to improve the adhesion between the coating and the substrate, the electroplated pure copper was coated as the bottom layer, then the nickel and the diamond were compositely electrodeposited. The effects of current density, stirring speed, and diamond concentration in the electrolyte on the mechanical properties of the coating were investigated. The content and distribution of the incorporated diamond were analyzed by electron microscopy. It was found that, with the increase of current density, stirring speed, and the concentration of diamond in the electrolyte, the diamond content of the coating increased first and then decreased. When the parameters were: 200 rpm, 1.33 A dm −2 , 10 g l −1 , the content of the incorporated diamond in the coating became the densest and most uniform one, which enhanced the hardness and the wear resistance of the coating and reduced the roughness of the workpiece. The result of the wear test indicated that no coating composition was transferred to the glass ball, which meant the coating did not contaminate the glass material. The unique press-in mechanism protected the pull-off of the diamond and prolonged the tool's service life. The rebounding mechanism of the coating was also feasible to the machining process of the glass, which could avoid the fragment of the thin glass. The use of the composite electrodeposition technique can remarkly reduce the manufacture cost of the micro-milling tool and, in the mean time, improve the machininng efficency and quality of hard and fragile materials.
