Electrophoretic deposition consisting of bioglass (BG)–chitosan (CS)–iron oxide nanoparticles (Fe3O4 NPs) on the Ti–13Nb–13Zr substrate was described. The bioactive coating was embedded in a CS matrix. The Fe3O4 NPs collected using the co-precipitation method varied at three different levels (1, 3, and 5 wt%) in the BG coating. The formulated coatings exhibited a hydrophilic character due to higher surface roughness values. The pull-off tape test was performed to check the adhesion strength of coatings. The composite coatings displayed adhesion strength of 5B class. The corrosion behavior was evaluated in Ringer's solution by the electrochemical test. The corrosion results showed that the composite coatings were more impressive as compared to pure BG and Fe3O4 coatings. The hemocompatibility results showed a hemolytic ratio (<5%), which validates them as favorable blood compatible nature of the deposited coatings. The findings exhibited that the BG–Fe3O4–CS coating can be widely employed as a favorable material for orthopedic applications.

Some interesting properties such as superelasticity, shape memory effect, kink resistance, good biocompatibility, biomechanical properties, and corrosion resistance made nitinol a popular biomaterial as stent and orthopedic implants. But surface modification is needed to control nickel leaching from its surface, making safe for human body. The aim of this study was to modify the nitinol surface by the silanization technique and electrophoretically deposited hydroxyapatite coating, and to conduct a detailed in vitro and in vivo investigation. Detailed in vitro investigation involved MTT assay with the human osteoblastic cells (MG63 cell) over a period of 5 days and confocal image study. In case of in vivo study, histological study, fluorochrome labeling study, and Micro-Ct study were conducted. The overall in vitro and in vivo results indicate that silanized nitinol samples are showing slightly better level of performance, but both the surface-modified samples are suitable as the potential bio-implant for orthopedic purpose.

Nano-structured yttria stabilized zirconia (YSZ)/Al2O3 nano-composite coatings were prepared by electrophoretic deposition (EPD) in acetyl-acetone/ethanol solvents under the constant voltage of 40 V. High sintering temperature may damage the metal parts and also lead to high production costs. To overcome the disadvantages of high sintering temperatures, reaction bonding of Al was taken as the approach. It was found that a powder mixture of Al and YSZ can lower the sintering temperature. YSZ/Al green composites were deposited on the MCrAlY layer applied on Inconel alloy cathode. Iodine was added to the solutions as the stabilizing agent. According to differential thermal analysis (DTA) results, embedded Al particles oxidation started at 660 °C. Sintering process for YSZ/Al2O3 nano-composite coating occurred at 1150 °C for 4 h. A lower pinholes coating with the highest density due to the constraint of the substrate was obtained.

The development of energy storage device utilizing carbon nanomaterials possesses remarkably significant electrochemical performance. As compared to others, carbon nanomaterials including carbon black, graphene, activated carbon, and carbon nanotube have advantages in ion accessibility and specific surface area in which, more charged ions can access and transfer to the surfaces of material and thus have enhanced electrical charge storage performance. This manuscript briefly reviews the deposition of carbon nanomaterials from electrophoretic deposition technique which is good because of its simple, economical, versatility, and possibility of the thin film deposition on large substrate. The current state-of-the-art and performance of devices employing carbon as electrode material is also extensively discussed.
