%X The electrodeposition of Ni/TiC nanocomposites on a rotating disk electrode in the presence of a cationic dispersant is modeled. In the proposed mechanism, TiC nanoparticles are transported through the diffusion layer, adsorbed on the electrode surface and incorporated into the growing nickel film if the residence time a particle on the surface exceeds the burial time. Therefore, TiC incorporation rate is proportional to the residence time and the total number of particles on the surface, whereas it is inversely proportional to the burial time. In the model, residence and burial times of a particle are defined as a function of the current density, hydrodynamics, particle size and dispersant concentration. And so, TiC incorporation rate and TiC vol% in the deposit are predicted as a function of TiC and dispersant electrolyte concentrations, current density, and electrode rotation speed. The model proposes that the addition of the dispersant increases the TiC amount in the deposit through increasing the residence time of a particle
