Effect of SiC concentration in electrolyte on Ni–SiC composite coating properties

Abstract

In the present study, a nickel sulphate bath containing SiC particles between 0?5 and 5?0 mm has been used as the plating electrolyte to obtain Ni-SiC composites on copper surfaces with high hardness and wear resistance for using in antiwear applications such as dies, tools and working parts of automobiles. The influence of SiC concentration in the electrolyte on morphology, microhardness, friction coefficient and wear missing volume of coatings has been studied. The coatings were analysed with scanning electron microscopy as well as X-ray diffraction. The findings indicate that increasing the concentration of SiC particles in the Watts bath results in improving the microhardness of coatings and also decreasing the friction coefficient and wear missing volume. Increasing the presence of SiC particles not only decreases the grain size of Ni crystals but also changes the morphology and preference orientation of Ni crystals.

Producing cobalt–graphene composite coating by pulse electrodeposition with excellent wear and corrosion resistance

“…Nanoparticles are always used to be incorporated in metal and metal alloy coatings to enhance their mechanical and chemical properties [3][4][5][6][7][8]. Aghaie et al [4] electrodeposited Ni-SiC composites on copper surface and found that increasing the concentration of SiC particles in the Watts bath results in the improvement of coating microhardness and the decrease of the friction coefficient and wear missing volume.…”

“…Aghaie et al [4] electrodeposited Ni-SiC composites on copper surface and found that increasing the concentration of SiC particles in the Watts bath results in the improvement of coating microhardness and the decrease of the friction coefficient and wear missing volume. Kasturibai et al [5] found that the microhardness and corrosion resistance of Ni-Si 3 N 4 nanocomposite coating were higher and better than those of the pure Ni coating.…”

Preparation of Oil-Encapsulated Microcapsules and Tribological Property of Ni Composite Coating

“…In literature, the microhardness, corrosion, and wear-resistant properties of electrodeposited Ni coatings have been increased by incorporating abrasive particles like alumina, diamond, SiC, ZrC, ZrO 2 , etc. [1][2][3][4][5][6][7][8][9]. However, the COF of such coatings has always been higher.…”

Preparation of a Microprism Ni-Ceo2Nanocomposite Mold by Electroforming

“…This phenomenon demonstrates that the weight percent of the CeO 2 nanoparticles embedded into the composite electrodeposits is significantly affected by current density. Many researchers also stated that the embedded nanoparticle content reduced with a rise in the current density [13][14][15].…”
