“…Silicon carbide (SiC) micro-and nano-particles are of considerable interest as the reinforcing phase [3,4,7,8]. The matrix phase studied so far has been mainly Ni and its alloys [3,[9][10][11][12][13][14], whereas much less has been reported on SiC co-electrodeposition with Zn [15][16][17][18].…”

Zn–SiC nanocomposite coatings were electrodeposited from aqueous citrate electrolytes using either direct current deposition (DCD) or pulsed electrodeposition (PED). The effects of various surface-active organic compounds (SDS, gum arabic, gelatin, CTAB, PEG 20000, and Triton X–100) on the coatings’ surface morphology and chemical composition were studied. The influence of pulse frequency and duty cycle on the percentage of the SiC nanoparticles (NPs) incorporated and on the quality of the deposits was also investigated. The amount of SiC NPs incorporated in the Zn matrix was similar for layers obtained by DCD compared to PED. The Zn–SiC coating deposited by PED exhibited a more fine-grained surface morphology. The percentage of SiC co-deposited with Zn was mainly affected by the type of surfactant used. The ionic surfactants (cationic gelatin and CTAB or anionic gum arabic) allowed the co-deposition of considerably higher amounts of SiC NPs with Zn, compared to the non-ionic compounds PEG 20000 and Triton X–100. However, the use of high molecular weight organic compounds such as gelatin and gum arabic led to aggregation of SiC NPs within the Zn matrix.

“…• Reinforced SiC particles act as a physical barrier to initiation and development of defect corrosion resulting in improvement in corrosion resistance [156] • Exhibited maximum hardness and wear resistance compared to pure nickel. [157] • Reported significant improvement in mechanical properties including hardness, yield, and tensile stress.…”

A number of processes are used for the preparation of composite materials depending on the required properties and choice of material system. Some of these are mentioned here such as Al-SiC, Al-Al 2 O 3 , Mg-SiC, Mg-Al 2 O 3 of high specific strength , stiffness, temperature resistance, low thermal expansion coefficient, wear resistance and thermal conductivity are prepared by fusion infiltration, extrusion, forging, gravity and die casting while PbC and Pb-Al 2 O 3 for high stiffness and creep resistance are prepared by fusion infiltration only [13]. Cu-W for burn up resistance and Pb-C and Brass-Teflon for load carrying capacity and wear resistance are prepared by powder metallurgy and infiltration. Similarly Equal Channel Angular Pressing (ECAP) for Al-Al 2 O 3 , High Pressure Torsion (HPT) for Cu-Fe composite, Hot pressing for Cu-Al 2 O 3 composite, hot extrusion for Mg-Al 2 O 3 , Sintering for Cu-MgO, Microwave sintering for Co-WC, Plasma spraying for Al-CNT, High velocity oxyfuel spraying (HVOS) for Ni-Al 2 O 3 , Cold spraying for Co-WC. Some other techniques such as spark plasma sintering, sol-gel and electrodeposition are also available for the preparation of metal matrix nanocomposites.

“…Electrodeposition of MMCs with SiC reinforcement has already been widely studied, mainly with Ni matrices. [5][6][7][8][9][10][11][12][13][14][15][16] Zinc-based coatings are widely used for cathodic protection of steels from corrosion, due to their low cost and environment compatibility. 1 Zinc, however, has low hardness and low abrasion resistance, which can be improved by its reinforcement with ceramic particles.…”

Zn-SiC nanocomposite coatings are successfully produced by galvanostatic electrodeposition from aqueous citrate solutions, using SiC nanoparticles (NPs) with an average size of 56 nm. The optimal parameters of the zinc-citrate bath are chosen on the basis of analysis of a thermodynamic model. The effect of applied current density, bath composition, and hydrodynamic conditions are studied. The kinetics and mechanism of zinc reduction in the presence of SiC NPs are investigated using cyclic voltammetry. The surface charge of SiC NPs suspended in the electrolyte solutions is examined by the dynamic light scattering technique. The electrodeposited Zn-SiC coatings are characterized by wavelength dispersive X-ray fluorescence and scanning electron microscopy. It is shown that SiC codeposition with Zn proceeds through the entrapment of ceramic NPs during the reduction of citrate-zinc ions that are first adsorbed on the surface of the ceramic NPs. A maximal content of 6.4 wt% SiC incorporated into the Zn matrix is obtained at the lowest applied current density of j =-0.5 A dm-2 , with a nearly constant faradaic efficiency of 90%.
