Electrodeposition of Ni composites and nanocomposites from aqueous organic solution

摘要

Electrodeposition of composites and nano composites composed of metal matrix (nickel) and inert particles (TiO2) has been carried out successfully in a mixed aqueous-organic solvent under different current densities. The ceramic particles are uniformly dispersed and embedded in nickel matrix. Titania content varied with its concentration in bath and with current density. SEM and XRD, EDAX studies have been performed to characterise the composites and nano composites. The particle size 60 - 1500 mn were obtained. In some cases preferred orientation of nickel has been observed. The TiO2 content ranged between 3.02 to 11.92 wt% in the composites.
