“…Similar observation has been reported in Refs. [1,13,15] and this is attributed to the change in deposition rate and particle concentration as deposition continues. The best quality films were obtained using 2 wt.% solids suspensions with 0.05% of OP.…”

EPD (electrophoretic deposition) technique has been shown as an effective method to produce thin ore thick layers at voltage 5-100 V onto Ni conductive substrate. The aim of this study is to use the EPD method to fabricate films from suspensions BaTiO 3 . The effects of the EPD process parameters such as the suspension concentration, deposition time, electrical field strength on the specific EPD deposited weight, morphology particles were used. The surface microstructures of the as-deposited films were investigated by SEM (scanning electron microscopy). A homogeneous microstructure was obtained at applied electric field of 100 V and 1 min of deposition time at an electrode distance of 1.0 cm.

“…A recent study demonstrates that dispersion depends on the I 2 -solvent interaction [37], while results in table 1 verify that the amount of I 2 for each system solvent-particle should be optimised. In fact, the surface charge of the particles becomes positive whatever was their nature [19,[33][34][35][36][37][38][39][40][41][42][43][44], and the effective amount of I 2 added is related to the morphologic properties of the particles [38,58,85].…”

Electrophoretic Deposition (EPD) performance strongly depends on the particles surface chemistry and the ability to manipulate surface-liquid interfaces. In this study an extensive investigation of YBCO suspension in dry acetone, acetone-water mixtures and acetone-iodine is reported. Chemical instability of YBCO particles determines their colloidal behaviour. Charging mechanism of particles has therefore had to be deeply investigated for complete dispersion understanding. In order to determine the conditions of the YBCO suspension stability, measurements of pH, conductivity, zeta-potential, settling tests, modelling of the particle networks and electrophoretic deposition were done. The influence of the water and iodine concentration, and their role as stabilizers was evaluated. Based on experimental results, pair particle potentials were calculated and then different charging mechanisms of YBCO surfaces in acetone were proposed.

“…As summarized in Table 1, several papers have been published on this topic providing a variety of results [1,[6][7][8][9][10][11][12][13][14][15]. For example, Tang et al [6,7] stated that the pH value, ionic conductivity and viscosity are key factors of the EPD process.…”

“…The result reflected the synergetic effect of the viscosity and conductivity of the suspension as well as the surface electric charge of the particles in determining the deposition behavior of the particles. Santillán et al [10] indicated that the rheology of nanosuspensions is very important for the achievement of good-quality coatings by EPD.…”

Surface modification by means of nanostructures is of interest to enhance boiling heat transfer in various applications including the organic Rankine cycle (ORC). With the goal of obtaining rough and dense aluminum oxide (Al 2 O 3 ) nanofilms, the optimal combination of process parameters for electrophoretic deposition (EPD) based on the uniform design (UD) method is explored in this paper. The detailed procedures for the EPD process and UD method are presented. Four main influencing conditions controlling the EPD process were identified as: nanofluid concentration, deposition time, applied voltage and suspension pH. A series of tests were carried out based on the UD experimental design. A regression model and statistical analysis were applied to the results. Sensitivity analyses of the effect of the four main parameters on the roughness and deposited mass of Al 2 O 3 films were also carried out.The results showed that Al 2 O 3 nanofilms were deposited compactly and uniformly on the substrate. Within the range of the experiments, the preferred combination of process -4 g/cm 2 , respectively. A verification experiment was carried out at these conditions and gave values of roughness and deposited mass within 8% error of the expected ones as determined from the UD approach. It is concluded that uniform design is useful for the optimization of electrophoretic deposition requiring only 7 tests compared to 49 using the orthogonal design method.
