Effect of SiC nanoparticles content on hardness of Ni-SiC-Gr nanocomposite coating via electrodeposition process

In this research, Electrochemical deposition of Ni-SiC-Gr nano composites was studied. The watts bath was used for electrodeposition. The SiC and graphiteparticles were suspended in the electrolyte and stirred. The effects of SiC nanoparticles Content in bath on the composite coating were investigated. The X-Ray diffraction (XRD) an scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) metods were used to characterize the micro structure of deposited layer. The results showed that the microhardness the increases with increases in pif value. The coating that pericipitated at 25 gr/lit were maximum hardness. The results demonstrate the morphological properties and hadness of Ni-SiC-Gr nano composite coatings fabricated via electrodeposition were improved with increase SiC nanoparticles in the bath. also demonstrated the hardness of coatings were not related to the graphitparticles content in the composite coating.
