“…Toluene was also added to the powder suspension of the first and second layers. The important physical properties of ethanol, PEG [35] and toluene [36] for the EPD process are listed in Table 3. Numerous experiments were performed to obtain the best set of suspension properties (viscosity and dielectric constant) that allowed reasonable deposition time and high-green density.…”

Electrophoretic deposition (EPD) technique is used to prepare zirconia–alumina composite layers based on the principle of functionally graded materials (FGM). The FGM were prepared with five layers. The outer layer was composed of pure α-alumina to promote biocompatibility while the inner layer was stabilised zirconia (3Y-TZP), to benefit from its tough properties. The intermediate layers were stepwise graded layers. The stability of the EPD suspensions was the main challenge during the preparation steps. Due to availability and low cost, alcoholic solutions of polyethylene glycol (PEG) and toluene were used to control conductivity, dielectric constant and the viscosity of the suspension. The appropriately applied potential, (ζ), for the deposition of each layer, was achieved via gradation of the applied voltage, which was to optimise the packing of each layer and avoid cracking after sintering at 1500 °C. The cylindrical-shaped green specimens were obtained via deposition on graphite electrodes. A small amount of acetic acid was added during the deposition of the final outer alumina layer to introduce porosity, via the bubbling of acetic acid, to encourage osseointegration. The sintered specimens were implanted in rabbit tibial bone. In vivo histological tests showed the successful osseointegration of the implants to the rabbit bone.

“…This is expected as a longer coating time through EPD would reveal this effect. 32,33 As a consequence, by longer coating time, smoother surfaces with smaller roughness values and shorter wavelength of asperities is achieved which is expected to affect the boundary and viscous effects.…”

“…It can also be seen from previous work that the topography, thickness and tribological characteristics of deposited coatings can be easily influenced by altering some of the parameters of the process. [31][32][33] It is clear that EPD has advantages over CVD/PVD methods for deposition of nanostructured films. These include a simpler equipment and set-up, the fact that depositions can be applied at ambient conditions to avoid thermal distortion and ability to coat curved and complex surfaces such as piston skirt and gear tooth flanks.…”

Piston skirt to cylinder liner conjunctions are amongst the major contributors to frictional power losses of Internal Combustion Engines (ICEs). Efforts have been made to mitigate the frictional losses of these conjunctions by incorporating different technologies such as texturing and application of novel coatings. Any potential technology needs to provide adequate wear resistance as well as frictional reduction in order to be practically applicable. In this paper, the piston skirt of a gasoline engine is deposited by three different variants of Graphene Oxide (GO) coatings deposited using an Electro-Phoretic Deposition (EPD) method. Their tribological performance is benchmarked against uncoated steel and graphite coated aluminium skirts. These coatings are experimentally characterised in terms of asperity level friction, topography and wear resistance. The conjunction and system level performance of these coatings considering both boundary and viscous friction and system dynamics are then evaluated using a multi-physics tribo-dynamic model. Results show that by incorporating an appropriate GO coating, the frictional power loss of the piston skirt to cylinder liner conjunction can be improved by up to 14% whilst maintaining the wear resistance of the coating at the level of an uncoated steel surface.

“…In the first step a charged particles in a stable colloidal suspension are moved through the liquid due to electric field. In the second step the particles are deposited on an oppositely charged conductive substrate [12,13]. EPD enables production of a wide range of compact or porous nano and microstructures, from nanometric coatings up to 1 mm thick coatings.…”

Porous sio2/HAp coAtIngs on cp-tItAnIum grAde 1 surfAces Produced by electroPHoretIc dePosItIonPorous hydroxyapatite doped Sio2 coatings were electrophoretically deposited (EPD) on commercially pure titanium. The influence of EPD parameters on coatings quality was investigated. Microstructural observation was done using transmission and scanning electron microscopy as well as X-ray diffractometry.The coatings consisted of spherical micro and nanocrystalline hydroxyapatite (HAp) as well as amorphous Sio2 nanoparticles. The coatings exhibited open porosity with pore diameter up to 1 µm and due to presence of nanoparticles high surface development.It was found that application of Sio2/HAp coating increase corrosion resistance of titanium in Ringer's solution.
