The effects of pH, types of applied current, agitation method and time, additive on the amount of codeposited TiO₂ particles in the matrix were investigated. The deposition rates increased with increasing pH values, while the volume fraction of TiO₂ particles and the size of agglomerated TiO₂ particles in the composite decreased. The volume fraction of TiO₂ particles in the composite decreased when pulsed current of 50% duty cycle was used. And the size of agglomerated TiO₂ particles in the nickel matrix of pulsed current was smaller than that of DC current specimen. The volume fraction of TiO₂ particles in the matrix decreased with longer time by air agitation, but in case of using magnetic bar, volume fraction in the same range of time was relatively constant. The volume fraction of the electrodeposited Ni-TiO₂ composite in the solution containing 0.01 M Dimethylamine borane (DMAB) increased slightly with increasing agitation time regardless of agitation methods. Thermal stability of the electrodeposited Ni-TiO₂ composite increased with lower pH at the temperature range of 200~800℃, and the results showed that the amount of co-deposited TiO₂ relies more on the deposition rate than zetapotential of TiO₂ particles.
