Abstract. CoCr aloys are most common material used as implantable material because of it reduced cost and good mechanical properties. This work presents our results of obtaining biomimetic calcium phosphate coating of CoCr and to characterize the properties of such coatings. The coating was prepared by immersing the CoCr substrates into the simulated body fluid (SBF) containing Ca 2+ ions in sealed plastic bottles, kept at room temperature for one, fourteen and twenty one days. Detailed characterization including chemical, structural and morphological characterization (SEM, EDS, X-ray diffraction) were perfomed. ICP/MS (inductively coupled plasma mass spectrometer) determinations sustain chemical results put in evidence by Fourier Transformed Infrared Spectroscopy (FTIR), the ions release being much smaller for phosphate coatings formed after longer immersion time in SBF. The hydrophilic/hydrophobic character of the coatings was put in evidence by contact angle measurements (CA).

“…Carbon nanotubes (CNTs) have already shown their potential as effective reinforcements for HAp and other ceramics [145][146][147][148] to improve fracture toughness. Reports are available on the processing of HAp-CNT composite coatings for orthopedic implants through plasma spraying [149][150][151][152], laser surface alloying [153,154], electrophoretic deposition [155,156] and aerosol deposition [157]. In addition to conventional sintering [158,159] and hot isostatic pressing [160,161], spark plasma sintering (SPS) [161][162][163] has also been employed to fabricate free-standing HAp-CNT composites.…”

“…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). HA/CNT composites comprising HA nanoparticles (20-30 nm) and high aspect ratio MWCNTs (10-30 nm in diameter, up to 500 mm length and 40-300 m 2 g 21 surface area) have also been developed by EPD (Kaya et al 2009).…”

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.
