  4. Abstract:
  5. In this study, titanium dioxide nano powders were electrophoretically deposited on the stainless steel in Isopropanol and Triethanolamine as a solvent and dispersant, respectively. The effects of deposition parameters including deposition voltage (5 to 20 V) and deposition time (5 to 60 s) on the microstructure and surface topography were examined by scanning electron microscope (SEM) and scanning probe microscope (SPM), respectively. In addition, the effects of these deposition parameters on packing density were investigated. This research revealed that substrate surface is fully covered with increasing deposition voltage and deposition time. Therefore packing density of deposited films is strongly dependent on the deposition parameters and reached its highest value at 20 V and 60 s. In addition, results show that surface roughness is increased by increasing the deposition voltage and deposition time. © 2008 World Scientific Publishing Company
