“…Hence it was concluded that plasma diffusion nitriding treatment and TiN deposition by chemical vapor process may be an interesting alternative to the physical vapor deposition technique [25]. The corrosion behavior of the TiN coated TiNi alloy was examined in 0.9% NaCl solution by potentiodynamic polarization measurements and polarization resistance method and the coating gave good protection to the TiNi alloy [26]. XPS spectra showed that TiN film consisted of 3 layers, a top layer of TiO 2 , a middle layer of TiN x (x > 1), and an inner layer of TiN, which agreed very well with results obtained by Oshida and Hashem [27].…”

Purpose The purpose of this study was to evaluate the surface characteristics and osteoblast cell response of TiN and TiAlN coated on Ti Surface. Methods TiN and TiAlN coatings were applied on Ti dental implant and surface characteristics of these coatings were evaluated. And osteogenic effect of TiN and TiAlN coating on MG63 osteoblast-like cell proliferation and differentiation was evaluated by cell viability assay (MTT assay), ALP activity assay and expressions of collagen gene. Results As observed by SEM, both the TiN and TiAlN coatings had thickness of about 1.7 µm. From the EDX analysis, Ti and N peaks and Ti, Al and N peaks are confirmed on the TiN and TiAlN coating surface, respectively. The wetting angles of TiN and TiAlN coatings were increased as compared to that of control Ti. As compared to Ti, a great number of attached cells on TiN and TiAlN coated surfaces were observed. The cell survival rate of the TiN and TiAlN were 125% and 117% as compared to that of the Ti (100%). Both the TiN and TiAlN coatings produced equivalent levels of protein. ALP activity of MG63 cells grown on Ti, TiN and TiAlN surface is indicated. Collagen gene was overexpressed in cells cultured on TiN and TiAlN in comparison with the Ti.Conclusions TiN and TiAlN coatings on Ti dental implant may have potential for use in dental implant in terms of their biocompatibility.

State of the art applications of polymers in medical implants cause in some cases problems due to their insufficient bio-and bloodcompatibility. On the other hand, titanium based materials are known to have bioinert properties.In order to combine the mechanical properties of polymers with the biocompatibility of titanium based materials, a new process for coating polymers with Titaniumcarbonitride(Ti(C,N))-layers by plasma assisted chemical vapor deposition (PACVD) has been developed.The in vitro bio-and bloodcompatibility is improved by the coating compared with uncoated PET and PP. It could be demonstrated that leaching of plasticizers (e. g. from PVC) can be prevented. Moreover PACVD is an excellent technique to obtain even coatings on complex substrates like textile implants.

“…Titanium nitrides are low-cost coating materials of choice owing to their enhanced tribology and biocompatibility 1,2 . Notable nanoscale titanium nitride applications are diverse, such as catalysts increasing durability in proton exchange membrane fuel cells 3 , prosthetic materials in total hip and knee replacements 4 and utilization in medical tools 5 such as vascular stents 6 and, lately, plasmonic materials with improved optical properties in the visible and near-infrared regions 7,8 .…”

The synthesis of nanosized Ti-based nanogranules via plasma spraying is reported. The synthesis route involved use of both nitrogen and oxygen gases with varying results. On the case of nitrogen, a mixture of titanium nitrides were produced, yielding both the Ti 2 N and the sub-stoichiometric TiN 0.61 compounds. On the case of oxygen, both the stoichiometric rutile and TiD ceramic phases were indexed. Based on EDS analysis, even fractional oxygen concentrations caused tungsten impurities which originated from the cathode electrode. The method yielded particle mass median sizes of the order of 15nm and the smallest particles detected were 5nm.
