“…The presence of some particles inside the pores would appear to result from the solvent drying, as already observed by some authors [35,36]. This result is consistent with what was reported by Fori et al [18] and argues in favour of using an electric field to improve the insertion of boehmite nanoparticles into the pores.…”

“…Fori et al [18,19] responded to this issue by using an organic based dispersion of SiO 2 particles, leading to complete filling of the pores, thus successfully avoiding side reactions such as solvent electrolysis. Despite the difficulties encountered in using an aqueous medium for EDP, Kusdianto et al [20] reported the potential to fill pores of less than 1µm in length using a pulsed electric field to limit water splitting, while Escobar and al.…”

International audienceThe present study investigates the pulsed electrophoretic deposition of boehmite particles, previously dispersed in an aqueous solution, into the pores of a model anodic film, prepared using phosphoric acid electrolyte, on an aluminium alloy 1050 (AA1050) substrate. Particles were successfully inserted into the pores, despite some limitations resulting both from the barrier layer, which transpired to be semi-conducting, and from water electrolysis. To address this issue, a pulsed electric field, set to above a threshold value, allowed a current to be sent through the cell, this being accompanied by a reduction of water electrolysis; insertion of particles thus became possible. Scanning Electron Microscope (FEG-SEM) observations, X-Ray Diffraction (XRD) spectroscopy and Electrochemical Impedance Spectroscopy (EIS) studies gave some clues as to the reality of particle impregnation into the pores. Furthermore, an improvement in the porous anodic film filling was achieved using hydrothermal post-treatmen

This chapter deals with the study of the elaboration of a stable suspension of TiO 2 nanoparticles and their incorporation by electrophoretic deposition into pores of anodized 5754 aluminum alloy. The as-synthesized TiO 2 nanopowder was characterized by X-ray diffraction, scanning and transmission electron microscopy (TEM), and infrared spectroscopy. During this work, transmission electronic microscopy (TEM) analysis showed that the resulting particles had a narrow size distribution with crystallite size of about 15 nm. The zeta potential and stability of TiO 2 nanoparticles dispersed with poly(acrylic acid) (PAA) in aqueous solution were also measured. Porous anodic film was elaborated in phosphoric acid electrolyte and then filled by TiO 2 particles using electrophoresis method. Furthermore, the effect of PAA content and pH on the suspension stability has been investigated. It was also demonstrated that buffered suspension by adding glycine avoids gelating phenomena which inhibits the insertion of nanoparticles inside the pores of anodic film. It was noted also that the electric field already applied greatly influences the electrophoretic deposition process (EPD). FEG-SEM observations showed that larger (125 nm diameter) and linear pores of 6 μm in length are successfully filled in 5 min. Finally, the composite anodic film tribological behavior was studied and the obtained results revealed that the insertion of the TiO 2 nanoparticles into the pores of the anodic film improves its tribological properties.

Conventional direct current (DC) and pulse-DC assisted electrophoretic depositions of colloidal particles, with average sizes of 10 and 50 nm, into sub-100 nm scaled pore arrays made from anodized aluminum substrate has been investigated. At the applied voltages lower than the decomposition voltage of water (~1 V), the number concentration of particle deposited on the surface by conventional DC was higher than that of pulse DC. The number of deposited particles increased with increasing pH. Deposition efficiency inside the pores can be enhanced by applying pulse DC. In the case of high (~10 V) applied voltage, no particles were observed inside pores even though pulse DC has been applied. The adhesion strength (removal behavior) of deposition was evaluated by applying a particle detachment simple system based on ultrasonic energy. The particles deposited
