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 pressur...

Aluminum coating was prepared on AZ91D magnesium alloy substrate using the electrophoretic deposition (EPD) method in absolute ethanol solvent. In order to determine the optimal concentration of AlCl3.6H2O additive, the zeta potential and size of particles in the suspension were measured in the presence of different concentrations of AlCl3.6H2O. The results showed that an appropriate coating is...

Ceramic coatings for metallic interconnects play a key role in limiting corrosion and chromium evaporation solid oxide cells. This study presents the upscaling of electrophoretic deposition (EPD) technique to process Mn-Co spinels on real-dimension Crofer 22 APU test SOFC stack. Area specific resistance long-term conducted 5000 h at 850 °C demonstrated that two-steps sintering has significant i...

A simple, rapid, and precise dynamic coating capillary electrophoretic separation method for water-soluble humic substances is proposed. An aqueous solution containing hydroxyethyl cellulose (HEC), polyethylene glycol (PEG), and pH buffer component was employed for both the dynamic coating agent and the separation medium. The procedure for the coating of the capillary inner wall was simply fill...

Titanium and its alloys have good biocompatibility with body cells and tissues and are widely used for implant applications. However, clinical procedures place more stringent and tough requirements on the titanium surface necessitating artificial surface treatments. Among the many methods of titanium surface modification, electrochemical techniques are simple and cheap. Anodic oxidation is the ...

The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...

The quartz-crystal microbalance is a sensitive and versatile tool for measuring adsorption of a variety of compounds (e.g. small molecules, polymers, biomolecules, nanoparticles and cells) to surfaces. While the technique has traditionally been used for measuring adsorption to flat surfaces and thin ridged films, it can also be extended to study adsorption to nanoparticle surfaces when the nano...

A method for silica-coating at the nanoscale by electrophoretic deposition is presented here, using raw or grafted silica dispersions.
