“…Commercial electrolytic baths such as nickel, chromium, copper, and zinc are the metallic matrix, and the dispersed phase is an insoluble solid with nanometric particle size and known morphology, which remains on the cathode surface by agitation and overgrown with the metal electrodeposition [4]. Since the 1970s, the electrodeposited composite coatings have been improved and have been published in some theoretical models that describe the adsorption and electrophoretic migration of particles, until the incorporation of a corrective factor to account for the efects of adsorption and hydrodynamic conditions [5].…”

“…Diferences in the diamond to nondiamond ratio of carbon forms modiied the adsorption characteristics and the quantity of diamond particles in coating (0.2-1 wt%). Largest density of particles into the nickel coating was achieved with the minimum diamond to nondiamond ratio, improving wear resistance and microhardness from 250 to 440 kg/m 2 with respect to pure nickel coating [4]. Hard materials like WC and SiC in a nickel matrix are used in engine block of aluminum alloys with good results in abrasion protection.…”

Electrodeposition is a low-cost and low-temperature method for producing metal matrix composite coatings. The electrodeposition of Ni matrix/Ni-Cr-B particles is considered as the co-deposition of Ni-Cr-B particles in a Ni matrix, resulting in nanocomposite coatings that can ofer good wear and corrosion resistance between other applications. For comparison, the electrodeposition of Ni ilms and their wear and corrosion evaluation were also carried out under the same conditions. Some coatings usually contain oxide or carbide particles in micrometer size and are electrodeposited in a nickel matrix; however, the use of the mechanical alloying process ofers the possibility to reduce the particle size in the order of nanometers obtaining solid solutions, amorphous phases, or intermetallic compounds during the development of new alloys to be co-deposited, improving the engineering materials properties. This kind of nanocomposite can be used in industrial components with an irregular geometry exposed in aggressive environments such as the energy generation and oil industry.

“…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].…”

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.
