【 摘 要 】

This paper presents our preliminary investigation on the deposit growth characteristic of FeCoNi nanoparticles prepared using potentiostatic electrodeposition. The FeCoNi electrodeposition was conducted in sulfate electrolyte containing cetyl trimethylammonium bromide (CTAB). Prior to the deposit preparation, cyclic voltammetry analysis was carried out to determine co-deposition potential of iron, cobalt and nickel ions. Mechanism of the deposit growth was studied based on the recorded potentiostatic current transient. The (i/im ) versus (t/tm ) plot indicated that nucleation and particles growth of FeCoNi was found to follow the instantaneous type closely, but with a very fast particle growth phase before entering diffusion stage. This growth characteristic produced fine nanoparticles of FeCoNi with homogeneous size distribution.
