“…The higher R pore value of Ni–W/GNP reveals that the uniform co‐deposited nanoplatelets distort the diffusion path of corrosion ions and act as a physical barrier against the expansion of defect corrosion due to the fact that GNPs could reduce the number of defects in the Ni–W matrix. [ 37,38,41 ] Among all the EC parameters in this study, it is worth noting that R ct is the key parameter to evaluate the corrosion behavior of coatings, which represents the resistance of metal atoms ionization in the corrosive medium. The higher value of R ct reveals that Ni–W/GNP coating has better anti‐corrosion property compared with the Ni–W coating.…”

Metal enhancement is crucial for reducing energy use and material waste. Composite electrodeposition is an economic and efficient method for improving the surface properties of metals. Herein, Ni–W matrix composite coatings reinforced with graphene nanoplatelets (GNPs) are prepared on 7075 aluminum (Al) alloy plates by the co‐deposition technique. Characterization results reveal that the mechanical properties and corrosion resistance of the coating can be improved by the successful embedding of GNPs. The Ni–W/GNP coating exhibits rougher, cauliflower‐like morphology, higher microhardness (782.6 HV), lower wear rate (2.72 × 10−5 mm3 N−1 m−1), and better corrosion current density (18.19 μA cm−2) compared with the Ni–W coating (578.2 HV, 7.43 × 10−5 mm3 N−1 m−1, and 25.16 μA cm−2, respectively). Moreover, X‐ray diffraction (XRD) spectroscopy and analysis verify that the grain size is decreased for GNP‐reinforced composite coatings with a typical Ni‐based solid‐solution phase.

“…The multilayers with individual layer thickness between 6 and 1 μm showed improved wear resistance even compared to the crystalline single layers, due to the decreased tensile stress within the crystalline Ni-P layer [505]. Reinforcement effect of Ni-P coating by electro-co-deposition of ZrO 2 -TiO 2 was reported [506]. The properties of Ni-Co-P multilayers with various Co/P ratio were tested and compared [507], and it was found that the coatings with submicron/ nanometric layers exhibited lower mass loss and COF in the range of 0.34-0.4 against a steel ball.…”

“…Considering the dislocation theory, the uniformly diffuse allocation of particles within the metal will show a great hindering difference on the dislocation slip between crystals. The strengthening of a coating by the cutting or by-passing effect of dislocations on particles is called diffusion strengthening [17]. When the amount of ZrO 2 particles increases, the addition of ZrO 2 in the Ni/W-ZrO 2 coating also increases.…”

Aluminum alloy has limited its application due to low hardness and poor wear resistance. Therefore, surface modification by electroplating is beneficial to improving hardness and wear resistance properties. Hence, Ni/W–ZrO2 coating was organized on aluminum alloy by electro-deposition method in this paper. The optimum organization parameters were obtained. The impact of different ZrO2 additions on the hardness and friction wear properties of Ni/W–ZrO2 coatings were further investigated. The SEM, Vickers examiner and wear examination are used to analyze the micromorphology, micro-hardness as well as friction and wear resistance properties, respectively. The results show that when the addition of ZrO2 was 40g/L in the deposition bath, the Ni/W–ZrO2 coating possesses the optimum micro-hardness of 384HV. This is mainly attribute to the dispersion-enhancing effect of ceramic particles. This work offers a new approach to surface strengthening technology for aluminum alloys.
