Abstract

Composite coating of tungsten carbide (WC) in the matrix of nickel has been achieved by direct current (DC) electrodeposition technique using a non aqueous bath. The deposition parameters such as current density, bath temperature, and stirring rate were maintained at constant levels for all the coating configurations. The composition of the coating and its microstructure were studied using energy dispersive x-ray spectroscopy, uv-vis spectrophotometry and x-ray diffraction, respectively. Surface morphology of the coatings was studied by scanning electron microscopy (SEM and TEM). Effect of heat treatment on the deposits microstructures and microhardness was also investigated. The Ni–WC composites, prepared at optimum conditions, exhibited improved mechanical properties in comparison to pure nickel electrodeposits.
