Electrophoretic Deposition of Titania Nanopowders

Abstract:

Titania Nanopowders were successfully deposited on stainless steel sheet by means of electrophoretic deposition method from titania suspension in which isopropanol was employed as a solvent and Triethanolamine as a dispersant. The effect of TEA addition on the stability of nanopowders in suspensions was examined by sedimentation test; in addition, Malvern zeta sizer was employed for determination their particle size. Electrophoretic Deposition was done at different deposition conditions of voltage (5-20 volts) and time (5-60 sec) and the scanning electron microscopy (SEM) was used to investigate the effect of suspension composition and deposition parameters on the microstructure of coatings. Furthermore, the effect of deposition parameters on the consistencies of different coatings was analyzed by Scanning Probe Microscope (SPM).
