Forming of Alumina Insulation Layers by Double Step Electrophoretic Deposition

Effect of ion concentration on viscosity, electrical conductivity and deposit weight of doped nano alumina prepared by electrophoretic deposition

Viscosity, electrical conductivity and deposit weight were determined for Electrophoretic deposition (EPD) Mg2+-, Y3+-, La3+- and Ce4+-doped alumina's ethanolic suspensions prepared at dopant concentration between 350 to 1350 ppm. The concentration of XCly (X, y were: Mg, 2; Y, 3; Ce, 3 and La, 3, respectively) the charging salt, is also found to be a critical factor to control the viscosity. I...

Electrophoretic Deposition of Hydroxyapatite

     The purpose of this study was to investigate the deposition of the hydroxyapatite (HA) coating via the electrophoresis procedure. The HA deposition was performed in an ethanol, methanol, acetone and isopropanol suspension. Methanol was found to be the best deposition media. Among the different environmental conditions, including the encapsulation of the samples under two vacuum types of pr...

Kinetic investigation of carbon nanotube deposition by DC electrophoretic technique

In this paper, kinetics of DC electrophoretic deposition EPD of carbon nanotubes CNTs is investigated. Carbon nanotubes suspended in pure ethanol with addition of magnesium nitrate was used as deposition media. The effect of main EPD parameters such as deposition time, applied voltage and the CNT concentration on deposit yield was investigated. The variation of current density vs. time and the ...

Multi-step Electrophoretic Deposition of α-Al2O3 Nanoparticles on Carbon Substrate (TECHNICAL NOTE)

in the present study, electrophoretic deposition (EPD) was used to obtain dense and crack-free layers of Al2O3 on carbon substrate. Microstructural study of the obtained layers by scanning electron (SEM) and optical microscopy (OM) approved that crack-free layers can be obtained by EPD technique. According to obtained results, isopropanol is a suitable media to obtian compact layers which is at...
