“…An efficient mechanical reinforcement of the HA layers can be obtained if the surface of CNTs has been functionalized not only to achieve a good dispersion of CNTs in the ceramic matrix, but also to induce an ideal interface between CNTs and HA. In one of the first published reports on this subject, CNT-reinforced HA layers on Ti -6Al -4V alloy substrates were obtained using sol-gel synthesized nanosized (20 -30 nm) HA particles mixed with multi-walled CNTs (MWCNTs) (Singh et al 2006). Subsequently, homogeneous HA/CNT composite coating layers were obtained using different EPD processing parameters (applied voltage and deposition time) (Kaya 2008;Kaya et al 2008 (Lin et al 2008a).…”

Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer-ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.

“…[18] Briefly, Ca(NO 3 ) 2 .4H 2 O and P 2 O 5 were used with a molar ratio of 10:3, to obtain the desired Ca/P ratio necessary for stoichiometric hydroxyapatite which is defined as a synthetic HA with a Ca/P molar ratio that approaches 1.67. 10 ml ethyl alcohol was used as solvent.…”

“…Results shown in Figures 5 and 6 are in good agreement with the data published in the literature. [18,19] This is a significant step towards obtaining HA coating layers that can be sintered at low temperatures, as low as 600°C, which do not cause substantial formation of residual stresses at the coating/ Ti6Al4V implant interfaces during the sintering process.…”

“…CNTs possess unique mechanical properties. However, there has been only limited work on incorporating CNTs in bioceramic coatings for biomedical applications [9]. The aim of the present work is to utilize cathodic EPD followed by sintering for fabricating bioactive monolithic HA and HA/CNT coatings on Ti6AI4V.…”

In order to improve the bone bioactivity and osteointegration of metallic implants, hydroxyapatite (HA) is often coated on their surface so that a real bond with the surrounding bone tissue can be formed. In the present study, cathodic electrophoretic deposition (EPD) has been attempted for depositing nanostructured HA coatings on titanium alloy Ti6AI4V followed by sintering at 800 o C. Nano-sized HA powder was used in the EPD process to produce dense coatings. Moreover, multi-walled carbon nanotubes (CNTs) were also used to reinforce the HA coating for enhancing its mechanical strength. The surface morphology, compositions and microstructure of the This is the Pre-Published Version.-2 -monolithic coating of HA and composite coatings of HA with different CNT contents (5 to 20%) on Ti6AI4V were investigated by scanning electron microscopy, energydispersive X-ray spectroscopy and X-ray diffractometry, respectively.
