The production of composite materials based on the second phase hard particles dispersed or deposited on metallic substrate is gaining importance for potential engineering application. In this study, electrophoretic deposition of B4C particles on nickel substrate was carried out at various voltage-time values. In order to determine the effect of medium on the deposition, the solution was prepared by different mediums and their effect on the stabilization was discussed. According to morphologic analyses, it was found that deposition of B4C particles on Ni surface has been occurred for all concerned applied voltage even at 10 V. However for lower voltage values, it requires prolonged deposition times. It was also observed that thickness of the deposited layer beneficially affected from the applied voltage, nevertheless the increase on the voltage resultant with un-favorable influence on surface, these are become heterogeneous and the electrolysis of water cause leak-like defects on the surface layers.
