Investigation of Electrical Resistance and Electrophoretic Deposition of Al2O3-TiO2 Nanoparticles in Different Alcoholic Environments

In this research, electrochemical deposition of alumina-titania nanoparticles in thin-film forms and in different alcoholic environments such as ethanol, butanol and isopropanol on Api5-GrB steel substrates was evaluated. Different voltages were applied to the coating, also chronoamperometry method was used in order to investigation of nucleation mechanism and quality of the coatings surface. Alumina-Titania nanoparticles, different alcoholic electrolytes (ethanol, butanol and isopropanol), dispersant particles (iodine) and Api5-GrB steel substrates were used as consuming materials. In the coating weight measurement test showed that the coatings weight increases with increasing voltage. With applying 30, 40 voltages, the maximum coverage was created in presence of butanol suspension but by increasing the voltage, the maximum cover was made in the presence of ethanol suspension.
