“…As is known to all, Carbon nanotubes (CNTs) are ideal metal-matrix reinforcers, which possess extremely high elastic modulus and strength, as well as thermal, electrical and absorbed properties [20][21][22][23][24]. CNTs could be deposited on substrates by the electrophoretic deposition (EPD) process, which is an effective method; as well, the thickness of CNTs can be controlled [25][26][27]. The accumulative rolling bonding (ARB) process is not only a traditional rolling deformation method, but also a metallurgical diffusion welding process [28,29].…”

The microstructure, electrical conductivity, and electromagnetic interference (EMI) shielding effectiveness (SE) of CNTs/Mg Matrix composites prepared by accumulative roll bonding (ARB) were systematically investigated to understand the effects of CNTs on the electromagnetic interference shielding effectiveness property of magnesium. A model based on the shielding of the electromagnetic plane wave was used to theoretically discuss the EMI shielding mechanisms of ARB-processed composites. The experimental results indicated that the methods were feasible to prepare laminated composites. The SE of the material increased gradually with the increase of electrophoretic deposition time. When the electrophoretic deposition time reached 8 min, the value of SE remained 87–95 dB in the frequency range of 8.2–12.4 GHz. The increase in SE was mainly attributed to the improvement in the reflection and multiple reflection losses of incident electromagnetic wave due to the increased amounts of CNTs and interfaces. The methods provided an efficient strategy to produce laminated metal matrix composites with high electromagnetic shielding properties.

“…The deposition of composite electrochemical coatings (CECs) is a reliable and economically feasible method for modifying metal surfaces in order to impart new functional properties to them [1][2][3]. Among the CECs, coatings based on nickel [4][5][6][7][8][9][10][11][12] and its alloys [13][14][15][16][17][18][19][20][21][22] have become widespread, which is due to the ability of nickel to form electrolytic deposits with dispersed particles of different nature which have good adhesion to the metal base [4]. It should be noted that the electrochemical deposition of alloys is one of the special cases of parallel electrode reactions with their significant mutual influence.…”

Composite electrochemical coatings (CECs) based on nickel-chromium alloy and modified with multilayer graphene oxide (GO) were obtained. The electrodeposition process of these coatings was studied in the potentiodynamic mode. The structure and the composition of nickel–chromium–GO CECs were studied by scanning electron microscopy and laser microspectral analysis. Nickel–chromium–GO CECs are dense and uniform. The carbon content in them increases when moving from the substrate to the surface. It was established that the addition of GO particles into the composition of electrolytic coatings with a nickel-chromium alloy results in the increase in their microhardness from 4423–5480 MPa to 6120–7320 MPa depending on the cathodic current density.

“…Therefore, CECs are used in various industries, and the development of new composite coatings is an important scientific and technical task. Among CECs, coatings based on nickel [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] and its alloys [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ] have become widespread, which is due to the ability of nickel to form electrolytic deposits with dispersed particles of a different nature which have good adhesion to the metal substrate. Nickel-based composite coatings are characterized by hardness and resistance in various corrosive environments.…”

“…The characteristics of the CECs are largely determined by the properties of the dispersed phase. Currently, a significant number of studies are devoted to the electrodeposition of composite nickel coatings modified with nanosized and nanostructured carbon materials: fullerene C 60 [ 4 ], carbon nanotubes [ 5 , 6 , 7 ], nanodiamonds [ 10 ], carbides [ 8 , 11 ], etc. Among the carbon compounds, graphite and its derivatives are of interest.…”

Nickel-based composite electrochemical coatings (CEC) modified with multilayer graphene oxide (GO) were obtained from a sulfate-chloride electrolyte in the reverse electrolysis mode. The microstructure of these CECs was investigated by X-ray phase analysis and scanning electron microscopy. The corrosion-electrochemical behavior of nickel–GO composite coatings in a 0.5 M solution of H2SO4was studied. Tests in a 3.5% NaCl solution showed that the inclusion of GO particles into the composition of electrolytic nickel deposits makes their corrosion rate 1.40–1.50 times less.
