Production of pulse electrodeposited Ni-TiC nanocomposite coatings

Abstract

In the present work, the Ni-TiC nanocomposites were electrodeposited from Watts' bath with suspended TiC nano-particles by pulse current (PC) deposition method. Effects of the peak current density on the TiC phase precipitation, surface morphology, crystalline size and the amount of co-deposited TiC nano-particles were investigated. TiC nano-powders were co-deposited with nickel matrix on the copper substrates. The characterization of the coatings was performed by scanning electron microscopy (SEM), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDS) and Vicker's hardness test methods.
