“…Therefore, to meet the demand for high-performance coatings in harsh environments, researchers have tried to incorporate nanoparticles into the Ni-W matrix to improve its corrosion resistance. In recent years, many studies have reported using Al 2 O 3 [15,16], SiC [17][18][19], TiN [20], ZrO 2 [21], BN [22], Si 3 N 4 [23] and other particles as the reinforcing phase to prepare metal matrix…”

Metal matrix composites have become a research hotspot due to their unique properties. In this paper, Ni-W-Carbon fiber (CF) composite coating was prepared by electrodeposition method, and the effects of CF content on the microstructure, composition, and corrosion resistance of the coating were studied by means of Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectrometer (EDS) and electrochemical testing by changing the concentration of CF in the plating solution. The results show that when 0.4 g/L nano-CF is added, the CF content in the composite coating is the largest and the distribution is uniform; the surface roughness Ra of the composite coating reaches a minimum of 14 nm. The electrochemical results show that the composite coating electrodeposited in the electrolyte containing 0.4 g/L nano-CF has the highest corrosion resistance. The Guglielmi model can be used to describe the co-deposition behavior. This study provides useful enlightenment for the further application of Ni-W-CF coating in harsh corrosive environments.

“…In recent years, researchers found that the hardness, corrosion resistance, wear resistance, physical and chemical properties of Ni-W metallic matrix could be improved by the addition of hard ceramic particles (e.g. TiN [5], [6], BN [7,8], WC [9], SiC [10][11][12], Si 3 N 4 [13][14][15], diamond [16], ZrO 2 [17], etc) into the alloy matrix. Several techniques have been used to fabricate Ni-W nanocomposite coating [18], in which the electrodeposition process is a convenient, low-cost, efficient and most widely applied method in various industries [19,20].…”

The effects of ZrO2, TiN, BN and Si3N4 nanoparticles on the microstructural, surface characteristics and properties of Ni-W composite coating have been comparatively studied in this paper. Their morphology, microstructure and characteristics were evaluated. Results illustrated that nanoparticles have been distributed in Ni-W composite coating, which could reinforce their properties. The surface topography was affected by the operating parameters. The formation of nodular protrusions could be attributed to the preferential discharge of the metal ions at the raised sites. The incorporation of nanoparticles could refine grains. The crystallite size of ZrO2, TiN, BN, and Si3N4 reinforced Ni-W composite coating were 13 ± 1, 13 ± 2, 12 ± 1 and 18 ± 1 nm, respectively. The roughness values (R a) of ZrO2, TiN, BN and Si3N4 strengthened Ni-W composite coating is about 50 ± 2, 70 ± 4, 89 ± 11 and 25 ± 1 nm, respectively. The corrosion-resistant and anti-wear capability have been enhanced by incorporating nanoparticles into the Ni-W alloy matrix. The strengthening mechanisms of the nanocomposite coating were proposed. These nanocomposite coating exhibit potential application advantages as protective coating with high performance in harsh conditions.

“…It has been reported that the employment of pulse current can significantly reduce the internal stress of electric casting compared with the conventional DC at the same average current density. Recently, Li et al [ 16 ] have studied the effect of pulse electroplating on the surface roughness of electrodeposited nickel films. Marro et al [ 17 ] also found the influence of pulse plating process parameters on the morphology and stress state of Cu film.…”

Tungsten-copper (W–Cu) composites are widely used as electrical contact materials, resistance welding, electrical discharge machining (EDM), and plasma electrode materials due to their excellent arc erosion resistance, fusion welding resistance, high strength, and superior hardness. However, the traditional preparation methods pay little attention to the compactness and microstructural uniformity of W–Cu composites. Herein, W–Cu composite coatings are prepared by pulse electroplating using nano-W powder as raw material and the influence of forward-reverse duty cycle of pulse current on the structure and mechanical properties is systematically investigated. Moreover, the densification mechanism of the W–Cu composite coating is analyzed from the viewpoints of forward-pulse plating and reverse-pulse plating. At the current density (J) of 2 A/dm2, frequency (f) of 1500 Hz, forward duty cycle (df) of 40% and reverse duty cycle (dr) of 10%, the W–Cu composite coating rendered a uniform microstructure and compact structure, resulting in a hardness of 127 HV and electrical conductivity of 53.7 MS/m.
