“…As the pH of the bath increases, the nodules of the coating gradually reduce, the nodule size of coating decreases gradually, and the coating surface becomes more uniform, flat and compact. The Ni-W-Co alloy prepared by Zhang et al[34] also obtained a similar conclusion. The morphology of Ni-W-Co alloy is related to the growth rate, and the growth rate is greatly affected by pH value.…”

“…The corrosion surface of the Ni-W coating at pH 8 is less porous than that at pH 7, but there are cracks, which is the reason for the poor corrosion resistance of the coating at pH 8. The higher the roughness, the greater the tendency to form metastable pits, thus increasing the likelihood of pitting [34]. When the pH of the plating solution is 9, the coating surface is relatively smooth and compact, and the coating has no obvious cracks or holes after corrosion.…”

According to the previous research, the hardness of Ni-W-Ti3C2TX composite coating is 24.3% higher than that of Ni-W alloy coating without adding Ti3C2TX. Meanwhile, the wear resistance and corrosion resistance of the composite coating are significantly better than that of Ni-W coating. It is known that the electrodeposition process parameters have a great influence on the performance. The Ni-W-Ti3C2TX composite coating was prepared by the direct current deposition method. The influence of bath pH on the morphology, composition, mechanical properties, corrosion resistance and friction resistance of the coating was systematically studied. The results show that the surface morphology of the coating is improved with the increase of pH value. The content of W in the coating decreases from 44.95 wt.% to 12.66 wt.%, and the grain size decreases from 77.1 nm to 8.9 nm. The hardness of the coating increases first and then decreases with the increase of pH under the joint action of fine grain strengthening and solution strengthening. When pH is 9, the corrosion resistance and tribological properties are the best, and the corrosion current density and wear rate are 1.782×10-3 mA•cm-2 and 0.865×10-6 mm3•n-1•m-1, respectively. A suitable pH value provides excellent surface quality, appropriate grain size and good hardness for the composite coating to show excellent corrosion resistance and friction resistance.

“…The XPS spectrum of Figure 2C shows the curve of Ni, while the peaks at a binding energy of 852.8, 854.5, and 861.0 eV were assigned to Ni, the Ni in NiO, and the satellite peak of Ni 2+ , respectively. [ 37,38 ] Besides, the peaks located at 73.0 and 73.4 eV are assigned to Al, while the peaks appearing at 74.5 and 75.3 eV belong to Al in Al 2 O 3 and AlO x , as shown in Figure 2D. As shown in Figure 2E, the peaks at 531.6 eV can be attributed to O in Al 2 O 3 bond.…”

This work presented a facile method to fabricate high‐white and robust superhydrophobic film on Al alloy surface. Ni/Al2O3 film with appropriate roughness and high‐white surface were constructed on the Al alloy by a simple chemical bath method via placing the Al alloy into the Ni2+ aqueous solution. Then the surface energy was reduced by spin‐coating the stearic acid (STA) to achieve excellent superhydrophobicity. As expected, the reflectivity, self‐cleaning, corrosion resistivity and mechanical durability of Al alloy after modification have all displayed dramatic enhancements. The reflectance of the modified Al alloy is far above the pristine Al alloy at all wavelengths (200‐2000 nm). This high‐white film with remarkable reflectivity can effectively reduce its surface temperature and improve visibility in practical application. Finally, a champion water contact angle of 161° and corrosion resistivity of 97.6% were attained by coating Ni/Al2O3‐STA composite film on Al alloy. The Leeb hardness of superhydrophobic film coated Al alloy was enhanced from 325 to 461 after coating superhydrophobic film on Al alloy. This work provides a framework for the development of superhydrophobic Al alloy with high‐whiteness and robustness.This article is protected by copyright. All rights reserved.

“…On the other hand, the growth thickness of Ni-Co-CeO 2 / Nip (4 g/L) composite coating was up to 30.3 mm within 30 min of electrodeposition, which indirectly reflected the deposition efficiency of the coating. Compared with electrodeposition, 11 scanning jet electrodeposition was more suitable for deposition under a high current density within a high-speed flowing electrolyte, which could timely supplement the ions concentration on the electrode surface. Therefore, scanning jet electrodeposition had the characteristics of fast and efficient manufacturing.…”

“…[1][2][3][4] Compared with the methods of magnetron sputtering, 5 plasma spraying, 6 and laser melting 7 to fabricate Ni-Co alloy coatings, electrodeposition has the advantages of mature technology, wide application range, moderate cost, precise control of coating thickness and structure. [8][9][10][11][12][13] There are some reports on nanoparticlereinforced Ni-Co composite coatings doped with nano-SiO 2 , 14,15 SiC, 16,17 ZrO 2 , 18 CeO 2 , 19 but the studies above are all immersion electrodeposition where samples were completely immersed in the electrolyte.…”

Jet electrodeposition has the characteristics of rapid deposition with high current density, but faces the problem of tip discharge, which causes a decrease in coating surface uniformity and flatness. In this paper, scanning jet electrodeposition was adopted to optimize the tip discharge. The different nanoparticles were mixed as the reinforcing phase of Ni-Co alloy coating. Nano-CeO2/Nip mixed particles enhanced Nickel-Cobalt composite coatings on 304 stainless steel by scanning jet electrodeposition. The morphologies, texture orientation, microhardness, coating adhesion, and corrosion resistance of Ni-Co-CeO2/Ni composite coatings were characterized. The addition of nano-mixed particles (CeO2/Nip) changed the morphology of Ni-Co-CeO2/Nip composite coating from large cellular protrusion structures to fine granular structures and improved the uniformity of the composite coating. Compared with Ni-Co alloy coating, the microhardness increased from 467.8 to 524.7 HV, the adhesion between the substrate and the coating increased from 20.6 to 28.9 N, and the corrosion current density decreased from 2.413 × 10−5 to 5.598 × 10−6 A·cm−2 in Ni-Co-CeO2/Nip (4 g/L) composite coating, indicating that nano-mixed particles (CeO2/Nip) improved the mechanical properties and corrosion resistance of Ni-Co alloy coating in scanning jet electrodeposition.
