“…Electrophoretic deposition has been used to deposit polymers [1], ceramics [2], metals [3], and combinations of different materials [4,5]. Currently, EPD is used in industry for the coating of primers on car bodies [6] and the deposition of phosphorus coatings for information displays [7]. New industrial applications such as e-ink displays [8] and electrophoretic deposition of dental crowns [9] also rely on EPD.…”

“…This deposition technique is widely used in industry [6] because it permits to obtain both greater thicknesses (more than hundreds of microns) and more compliant deposits than those achieved by dip-coating. However, EPD process is also known for obtaining thin and multilayer film of controlled thickness on substrates of complex geometry, which is particularly interesting for various applications including corrosion or wear protection.…”

a b s t r a c tThe realisation of organic/inorganic coatings on metal substrates, prepared by sol-gel route and shaped by electrophoretic deposition (EPD), is a new process which has been the subject of only few studies. In the past few years, EPD became a very interesting deposition technique because it showed some important advantages: i) great control of the deposition rate and ii) good coverage of complex shape parts. Both are the main challenges for all kinds of deposition techniques, used in various fields from anti-corrosion to anti-wear. In this work, the electrophoretic deposition was performed in aqueous sol suspension containing sol-gel boehmite nanoparticles (NPs). The influence of the applied voltage and deposition time on the deposit thickness was studied. The effect of the concentration of NPs, added in the precursor sol, on the thickness was also investigated. The deposition was performed at constant voltage between − 1.2 and − 3.5 V during constant deposition time between 10 and 40 min. It is shown that an increase in the applied voltage and deposition time increased the thickness of the deposit film (from 2 to 11 μm), as well as the amount of evolved hydrogen, resulting in a drop of the formed coatings quality (more porous structure). However, increasing the concentration of NPs in the precursor sol, increased the coating thickness and turned out to be also a key parameter to control the thickness. Finally, it was demonstrated that a perfect control of the microstructure and the deposit thickness was achievable, thanks to both EPD parameters and sol properties.

“…In the automotive industry, cathodic electrocoating is widely used as a primary layer coating in the corrosion protection system [1][2][3]. This deposition method has many advantages including high throw power, high corrosion protection and coating transfer coefficient (>95%), auto-limitation of the coating thickness, environmentally friendly due to an aqueous suspension medium and an easy industrial automation [4,5].…”
