“…It has been reported [44][45][46] that the effect of adding ceramic nanoparticles generally increases the roughness of metallic coatings obtained by electrodeposition. However, this effect depends on the amount and type of nanoparticle added, in addition to the coating composition.…”

Zn-Ni alloys have been used to decrease the corrosion rate of carbon steel substrates. These are used in applications such as bolt coatings, threaded parts, swift valves for gas pipelines, aircraft landing gear, brake system components and others. Zn-Ni coatings containing nanocrystals of cellulose (CNC) obtained from sisal fiber (Sif), a natural polymer, were manufactured using the electroplating technique. Obtaining the nanocrystals involved bleaching raw sisal fiber and then acid hydrolysis to extract the nanocrystal. The effect of the concentrations of the CNC-Sif (0% v/v, 2%v/v, 3%v/v, and 4%v/v) on the morphology and microstructure of the Zn-Ni coating was analyzed through Scanning Electron Microscopy (SEM), X-ray diffraction, and roughness measurements using confocal microscopy. The effect of the addition of CNC-Sif on the efficiency of galvanostatic deposition was analyzed. The corrosion rate through mass loss and electrochemical tests were also analyzed. The effect of adding CNC-SIF on coating microhardness investigated. This study show that the addition of nanocrystals alters the structure, the morphology, increases current efficiency and the corrosion resistance of the Zn-Ni coating and these effects are more significant with the addition of 2% v/v. The results obtained indicate that the addition of the CNC-Sif in the Zn-Ni coating is promising, because it reduces the energy consumed during the electrodeposition process in addition to increasing corrosion resistance of the Zn-Ni and the microhardness.

“…The improved corrosion resistance of Ni-GO composite coating prepared by jet electrodeposition may be due to the addition of GO, which refines the grains of Ni matrix metal of the composite coating, it reduces the cathode/anode surface ratio, thereby further preventing local corrosion and improving the corrosion resistance of the composite coating [37,38]. In addition, the presence of GO in the composite coating in the form of nanosheets reduces the effective contact area between the composite coating and the corrosive medium [14]. GO also has excellent barrier properties and the ability to make up for defects.…”

“…The common nanoparticles involved in nickelbased composite coatings mainly include nano-SiC [6], Al 2 O 3 [7], TiC [8], ZrO 2 [9], La 2 O 3 [10] and diamond [11], carbon nanotubes [12], graphene [4] and graphene oxide [13]. Research has shown that adding a small amount of graphene oxide (GO) can significantly improve many properties of the nickel composite coating, such as elastic modulus, electrical conductivity, yield strength, friction reduction, wear resistance, and corrosion resistance [13][14][15][16]. Common preparation methods of nickel-graphene oxide (Ni-GO) include traditional electrodeposition [13,14], ultrasonic-assisted electrodeposition [15], chemical reduction [16].…”

The Ni-GO-TiC nano-composite coating was prepared by scanning jet electrodeposition. The morphologies and microstructures of the composite coating were analyzed by FESEM and XRD, and the wear and corrosion resistance of the composite coating were studied. Studies have shown that the Ni-GO-TiC composite coating has a micro-nano ridge shape structure. The addition of nano TiC and GO does not change the structure but refines the grain growth of the Ni matrix metal. Nano TiC can effectively prevent GO from agglomerating, improve the dispersion, and further enhance the wear resistance of the Ni-GO-TiC composite coating. In addition, the corrosion resistance of the Ni-GO-TiC composite coating has also been greatly improved. Compared with pure Ni coating, the corrosion current density is reduced from 51.30 μA·cm-2 to that of the Ni-GO-TiC composite coating to 1.712 μA·cm-2. Nano-TiC and GO are used as reinforcing phases to refine the grains of the composite coating and effectively inhibit the penetration of corrosive media.
