The hydroxyapatite layer was deposited on the commercial magnesium alloy of AZ91 by electrophoretic deposition route, and corrosion behavior applied layers studied polarization electrochemical impedance spectroscopy at Simulated Body Fluid (SBF) solution. best resistance improvement obtained for sample synthesized 40 V within 4 minutes. Also, morphology coated samples atomic force microscopy (A...

Stable water soluble surfactant coated CdSe nanocrystals with trioctylphosphine (TOP) were obtained by a process of dynamic surface coating with cationic, anionic, and non-ionic surfactants. The surfactant-coated CdSe/TOP nanocrystals were characterized by complementary techniques of UV-VIS and photo-luminescence spectrophotometry, as well as by means of a capillary zone electrophoretic techniq...

This chapter reviews the novel fabrication process of continuous SiCf /SiC composites based on electrophoretic deposition (EPD). EPD process is very effective for achieving relatively homogeneous carbon coating with the thickness of several tens to hundreds nanometers on SiC fibers. Carbon interface with the thickness of at least 100 nm formed by EPD acts effectively for inducing interfacial de...

Several shortcomings of the alloys that are used to fabricate a number of currentgeneration biomedical implants, such as Ti-6Al-4V alloy for the femoral stem of a total hip replacement and AZ3 Mg alloy for the scaffold of a fully bioabsorbable coronary artery stent, are well-known. Examples of these shortcomings are limited bioactivity/osseointegration (in the case of Ti-based alloys) and high ...

In the present study, hydroxyapatite-titania-graphene oxide (HA-TiO2-GO) nanostructured ternary composites were deposited on Ti-6Al-4V alloy by using electrophoretic deposition. The well-dispersed stable suspensions of hydroxyapatite particles with 20wt.% TiO2 and 0, 0.5, 1 2 wt.% GO prepared deposition was performed at an optimum voltage 20 V for 90 s. A novel linear approach fracturemechanics...

BACKGROUND Plasma-spray deposition of hydroxyapatite on titanium (Ti) has proven to be a suboptimal solution to improve orthopedic-implant success rates, as demonstrated by the increasing number of orthopedic revision surgeries due to infection, implant loosening, and a myriad of other reasons. This could be in part due to the high heat involved during plasma-spray deposition, which significant...

PURPOSE Main aim of the present study was to test and show the dissolution of coatings onto Ti6Al4V pedicle screws by both in vitro and in vivo analysis. METHODS Hydroxyapatite (HA) was coated on Ti6Al4V by electrophoretic deposition (EPD). The dissolution of the coatings was tested in vitro. The coating was characterized before and after implantation via pull-out tests, X-ray diffraction (XR...
