“…All chemicals were analytic grade reagents. The particle agglomeration was prevented by suspending the SiC nanoparticles in the electrolyte bath under a magnetic stirring at 600 rpm for 24 hours before and was done during the plating 8 . The electrodepositing condition included a direct cathodic current density ranging 20 -50 mA/cm 2 , a depositing time of 60 min, an electrolyte speed of 600 rpm and temperature of 55ºC.…”

“…Yang & Cheng 3 prepared Ni-Co/SiC composite coatings by pulse current (PC) electrodeposition on X65 carbon steel and found that the coating morphology changes from a nodular to an acicular structure with finer grains besides the micro-hardness and corrosion resistance that was enhanced with the amount of SiC nanoparticles deposited. Bakhit et al 8 found that the highest percentage of SiC nanoparticles (8.1 vol.%) in the Ni-Co/SiC nanocomposite coatings was achieved at 2 A dm -2 deposition current density and 5 g L -1 particle concentration, in plates of brass as substrate. The author indicated that the corrosion resistance of the Ni-Co/ SiC nanocomposite coatings was markedly higher than the corrosion resistance of the Ni-Co alloy coatings.…”

“…Among the various composite coating systems produced by the combination of different matrix and reinforcement materials, Ni/SiC composite coatings have been widely studied in order to explore the impact of the co-deposition conditions and the properties of the deposited coatings. Recently, more attention has been paid to the synthesis of composite coatings by codeposition of reinforcing particles in the alloy matriced like Ni-W 5,7 , Zn-Ni 7,8 , Ni-Fe 9 and particularly Co-Ni alloys [5][6][7] . However, only few investigations have been made regarding the electrodeposition of Co-Ni/SiC nanocomposite coatings, which may feature favorable mechanical, corrosion and tribological properties 10 .…”

“…Besides that, Ni-Co metal matrix composite coatings have widely attracted attention due to its hardness and corrosion resistance as a replacement for hard chromium coating 2,8 . Ni-Co based composite coatings are expected to be applied in automobile, aerospace and other industrial fields owing to their good adhesion to the substrate's low residual stress, high hardness, anti-wear and anti-corrosion properties 6,7,11 .…”

Evaluation of Co-Ni/SiC Nanocomposite Coating Obtained by Electrodeposition on the Corrosion Resistance of API 5L X80 Steel

Co-Ni/SiC nanocomposite coatings were obtained by codeposition of SiC nanoparticles in a bath with nickel and cobalt, using API 5L X80 as the substrate. The influence of cathodic current density on deposit properties was investigated. Measurements of electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) were performed in 3.5 wt% NaCl solution to investigate a corrosion performance. The morphology and chemical analysis of the surfaces were analyzed by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) and related with micro-hardness and X-ray diffraction (XRD). The results indicate which composite coatings have acicular morphology, with higher micro-hardness values than those found for the carbon steel substrate. The Co-Ni/SiC coating increased the corrosion potential and the resistance to polarization, which resulted in lower corrosion rates than those obtained without uncoated steel.

“…It means that very high (positive or negative) values of S or j (out of the range of this work) can enhance the studied variable. An increase in S is related to the stability of the dispersion, while an increase in j is associated to the increase in the boehmite content in the coating 19,46,50 . Thus, a decrease of S or j may be related to a decrease in the boehmite in the coating.…”

In this work, composite coatings of Cu/AlO(OH) were produced by electrodeposition on steel substrates using a pyrophosphate-based bath containing allyl alcohol as an additive. The electrodeposition of the composite coatings was carried out using a 2³ central composite design (CCD), aiming to verify the effects of the deposition parameters (previous stirring time (t), the stirring speed (S) and the current density (j)), considered the entry variables, on the electrochemical behavior of Cu/AlO(OH) coating, the response variables of the CCD. The results indicated that a decrease of the parameters j and S directly influenced the values of R p and R ct , leading to the production of protective coatings. The best result (R p = 211 Ω and R ct = 221 Ω) was obtained under conditions where t = 120 min, S = 1300 rpm and j = 7 A m -2 . Dispersed bohemite particles could be noted on the surface of the composite coating.

Effect of Rough‐Surfaced Diamond Content on the Microstructure, Tribological Behavior, and Corrosion Resistance of Ni/Diamond Composite Coatings

This study fabricates certain Ni/diamond composite coatings using a coelectrodeposition method and then evaluates the effect of diamond content on the morphology, phase structure, microhardness, wear, and corrosion resistance of such coatings, while exploring their tribological and anticorrosion mechanisms. It is demonstrated that the addition of diamond can change the preferred orientation of Ni from (200) to (111), and its texture coefficient value can be boosted from 23.3% to 64.4% with the increase of diamond content. In the experiment, at a diamond content of 3 g L−1, the deposited diamond particles are more and evenly dispersed across the composite, with the microhardness of nickel‐based coatings reaching an optimum value of 613 HV. In addition, the coefficient of friction is reduced to a minimum value of 0.627, while the wear rate is kept at only 1.79 × 10−5 mm3 Nm−1, indicating a high wear resistance. Electrochemical test results demonstrate that the Ni/diamond composite coatings produced at 3 g L−1 create the maximum charge transfer resistance (5429.3 Ω cm2) and the minimum corrosion current density (2.19 μA cm−2), features that can deliver the best corrosion resistance.
