A Study of Ni-SiC Nano-Composite Plating Process

Ni-based coatings with nanometer SiC powder were made on copper substrate.The effects of cathodic current density,plating solution,pH value and temperature on the micro-hardness of Ni-SiC nano-composite coating and co-deposition rate are analyzed.And at the same time process parameters are optimized,and the surface morphology and energy spectrum of the Ni-SiC nano-composite coating are also analyzed.The experiment results show that the Ni-SiC nano-composite coating has a flat morphology and compact microstructure,and its micro-hardness is remarkably improved as compared with that of pure nickel coating.
