“…Electodeposition has been widly perform to produce CNT S metal matrix composites due to its operation in low cost and low temperature and CNT S have been successfully co-deposited into MMC using electrodeposition [39,40]. CNTs composite coatings contact surface is the worn surface were much smoothening due to the less plastic deformation [41].…”

The characteristics of Silicon carbide (SiC) and multi-walled carbon nanotube (MWCNT) nano composite coatings by a Pulse Reverse Electrodeposition (PRE) method is investigated in detail to enhance the microhardness (MH) and corrosion resistance characteristics of AISI 304 stainless steel substrate. The electrodeposition nature, dissolution behavior, surface characteristics are assessed by Scanning Electron Microscopy (SEM) with energy dispersive x-ray (EDX), x-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Microhardness (MH) Test and Electrochemical studies. The coatings are prepared in the watts type bath using pulse reverse electrodepositions (PRE) method of varying the electrolyte deposition parameters in different combinations. Present results clearly reveal that, there is a drastic improvement in the magnitude of microhardness of coated specimens, silicon carbide (SiC) and multi-walled carbon nanotube (MWCNT) composite coatings yield a maximum hike of 91.6% and 168% respectively. Furthermore, the Nyquist and impedance plots clearly depict that, multi-walled carbon nanotube (MWCNT) exhibits higher corrosion resistance characteristics. Recently, nanomaterial's like carbon nanotubes (CNTs) have gained significant focus as the incorporating filler to endow the composite coatings with functional properties such as smoothness [12], better hardness [12][13][14][15][16][17][18], lower coefficient of friction [13], better wear and resistance [12,15], corrosion resistance [14,19], higher compressive strength [16] and good flexibility [20,21].Carbon nanotubes (CNTs) [22, 23] possess excellent mechanical characteristics, such as high tensile strength, elastic modulus, thermal and electrical conductivity.

“…In contrast with the above methods, electrodeposition has been widely used to produce metal matrix composites due to its operation in low temperature conditions and low cost. The second phase, including SiC [4,5,6], TiO 2 [7,8,9,10], carbon nanotubes (CNTs) [11,12,13,14,15,16], and Poly tetra fluoroethylene (PTFE) [17], have been successfully co-deposited into a metal matrix using electrodeposition.…”

“…CNTs exhibit desirable electrical conductivity, thermal conductivity, and mechanical properties (tensile strength 1 TPa and tensile strength 63 GPa) [18,19], making them suitable as a reinforced phase in the metal matrix. Cu-CNTs composite coatings with high thermal conductivity, enhanced strength, and wear resistance have been extensively studied [11,12,13,14]. Conventional electrodeposition is usually used to prepare Cu-CNTs composite coatings.…”

Cu-carbon nanotubes (CNTs) composite coatings with high CNT content and uniformly distributed CNTs were successfully prepared via jet electrodeposition. Pristine CNTs, without any treatment like acid functionalization, were used. Anionic surfactant sodium dodecyl sulfate (SDS) was used to increase the wettability of the CNTs and improve the content of incorporated CNTs. With an appropriate SDS concentration (300 mg/L) in the electrolyte, the incorporated CNT content is as high as 2.84 wt %, much higher than the values reported using conventional electrodeposition (0.42–1.05 wt %). The high-content CNTs were uniformly distributed in the composite coating. The surface morphology of this composite coating (2.84 wt % CNTs) was flat due to the uniform electric field in jet electrodeposition. In the wear test a with load of 1 N and sliding speed of 0.02 m/s, the wear rate of this composite coating was 1.3 × 10−2 mg/Nm, 85.4% lower than that of pure Cu. The enhanced wear performance of Cu-CNTs composite coatings can be attributed to high CNT content and flat surface morphology.

“…The advantages of electrodeposition is an excellent low cost and low temperature technique compared to the conventional methods such as powder metallurgy, sputtering, spin coating, thermal spraying, centrifugal casting etc., which is used to coat over the complicated conductive surfaces. Electrodeposition is an industrially viable and economically preferable technique for the deposition of metals and alloys and metal matrix nanocomposites (MMNCs) [23][24][25][26][27][28][29][30][31][32]. The SiCnanoparticlesare very hard materials and possess high strength and high thermal conductivity, good corrosion and wear resistance and low cost material.…”

The Cu and Cu-SiCnanocomposite coatings were prepared by a simple electrodeposition technique from acidic copper sulphate electrolyte using SiC nanoparticles with an average particles size of 50 nm under optimized bath composition and preparation conditions for possible electrical contact material applications such as electrical switch and wiring boards where higher electrical conductivity and thermal conductivity is required. The scope of the present study is to enhance the strength, mechanical, corrosion and wear resistance properties of Cu-SiCnanocomposite compared to pure Cu coatings. The as prepared Cu and Cu-SiCnanocomposites were characterized for structural, mechanical and corrosion resistance properties by EDX, XRD, FESEM, Vickers microhardness tester and AC-impedance and Tafel polarization techniques. The elemental composition (wt% of Cu and SiC nanoparticles) of Cu-SiCnanocomposites was analyzed by EDX coupled with FESEM analysis confirms the presence of nanoSiC in the copper matrix and they were 89wt% of Cu and 11 wt% of SiC nanoparticles respectively. The surface morphology of Cu and Cu-SiCnanocomposites was studied by FESEM analysis shows that SiC nanoparticles were uniformly dispersed in the surface of the copper matrix compared to pure copper. The crystallite structure and grain size of the Cu and Cu-SiCnanocomposite electrodeposits was measured by XRD analysis. From the XRD results, the grain size calculated using Debye-Scherrer’s formula was ~35 nm for pure Cu and ~33 nm Cu-SiCnanocomposite. The crystallite structure of Cu and Cu-SiCnanocomposites was fcc (face centered cubic) and the preferred orientation of the plane was (220). The microhardness of Cu-SiCnanocomposite coating increased with increasing SiC nanoparticles concentration in the bath compared to pure Cu coating. The corrosion resistance measurements were performed for the pure Cu and Cu-SiCnanocomposite coatings by electrochemical impedance spectroscopy (EIS) and Tafel polarization techniques. It shows that, Cu-SiCnanocomposites has high corrosion resistance than pure Cu in 3.5wt% NaCl solution.
