“…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.

This paper aims at investigating the influence of process parameters on micro hardness of metal matrix / material particle coated steel plates. The electro deposition parameters such as current density, pH of bath, bath temperature, Al particles concentration in the bath and agitation speed were considered for this study. Nickel matrix / aluminum particle composite coatings were prepared from a Watt's bath by electro-codeposition method. The Taguchi method was used to establish the relationship between the process parameter and response variable, micro hardness of the coated plate. L27 Taguchi orthogonal design was employed for conducting the experiments. The micro-hardness of the deposits was examined using a Vickers micro-hardness tester with the payload of 100 g for 10 sec of indentation period. Signal-to-noise ratio and analysis of variance were employed to determine the significance of the process parameter. The surface morphologies of coating and vol. % of Al particles in deposits were analyzed using optical and scanning electron microscope observations.

“…This characterization is in line with the obtained results by [12,13] that particle agglomeration occurs when greater attraction than repulsion energy exists between them. Secondly, there is likely oxide growth at the surface of the metal due to the interaction of Zn with O 2− or OH − anions [1,17]. In view of this, Zr 4+ and Si cations may migrate from the oxide/metal interface to the electrolyte/oxide interface and are ejected into solution by an electric field.…”

“…However, the vulnerability of this metallic material to corrosion, hardness and poor wear resistance has been a major concern. In an attempt to provide suitable remedy by material experts, coating through electrodeposition route is known to be versatile [1][2][3]. The use of coating for metal protection against corrosion [1], aesthetic value and mechanical improvement had been widely studied [4][5][6].…”

In an attempt to improve the mechanical and thermal resilient properties of mild steel, Zn-ZrO 2 -SiC composite coating was fabricated from zinc-based sulphate electrolyte with incorporated composite particles of ZrO 2 /SiC at 2.0 A/cm 2 for 10 min. The effects of particle on the mechanical properties were examined using scanning electron microscope attached with energy dispersion spectroscopy and atomic force microscopy. The micro-hardness and wear resistance behaviour were determined with high diamond microhardness tester and three body abrasive MTR-300 testers with dry sand rubber wheel apparatus with 5 N. The fabricated coating was thermally heated at 200°C for 4 h to evaluate the coating stability. From the results, a modification in the microstructure and topographic orientation as a result of incorporated composite was noticed on the zinc matrix. The mechanical and thermal properties were observed to be considerably improved by the incorporation of the ZrO 2 /SiC weight fraction. A significant improvement in wear and hardness properties were also obtained for the multiphase embedded coatings.
