“…A TiN coating several micrometers thick deposited by ion plating onto a titanium prosthetic heart valve cage was first introduced by Mitamura et al [299]. Many of the papers that follow have focused on dental prostheses in which Co-Cr-Mo alloys are commonly employed [300][301][302][303].…”

Titanium and titanium alloys are widely used in biomedical devices and components, especially as hard tissue replacements as well as in cardiac and cardiovascular applications, because of their desirable properties, such as relatively low modulus, good fatigue strength, formability, machinability, corrosion resistance, and biocompatibility. However, titanium and its alloys cannot meet all of the clinical requirements. Therefore, in order to improve the biological, chemical, and mechanical properties, surface modification is often performed. This article reviews the various surface modification technologies pertaining to titanium and titanium alloys including mechanical treatment, thermal spraying, sol-gel, chemical and electrochemical treatment, and ion implantation from the perspective of biomedical engineering. Recent work has shown that the wear resistance, corrosion resistance, and biological properties of titanium and titanium alloys can be improved selectively using the appropriate surface treatment techniques while the desirable bulk attributes of the materials are retained. The proper surface treatment expands the use of titanium and titanium alloys in the biomedical fields. Some of the recent applications are also discussed in this paper. #

“…The excellent intrinsic biocompatibility of TiN has been well documented in biomedical applications [16,19,33]. Bactericidal kinetics and a low cytotoxicity are the two essential requirements for bactericide surfaces and long-term tests using the catalyst presented in this study are under way in our laboratory.…”

a b s t r a c tThis study presents the design, preparation, testing and characterization of TiN and TiN-Ag nanoparticulate films leading to photocatalytic and catalytic inactivation of Escherichia coli. When Ti was sputtered in N 2 atmosphere, the TiN films unexpectedly revealed semiconductor properties when irradiated under visible light due to the formation of TiO 2 showing absorption in the visible spectral region. In TiN-Ag films, Ag enhances the photocatalytic activity of TiN leading to faster bacterial inactivation. Evidence for the presence of TiO 2 and TiN in the films is presented by XPS. The TiN layers 50 nm thick sputtered by DC for 3 min led to complete inactivation of E. coli within 120 min. But TiN layers with a thickness >50 nm hinder the surface diffusion of charges reducing bacterial inactivation. The rate of TiN deposition was ∼1.4 × 10 15 atoms TiN/cm 2 s. For the TiN-polyester samples under visible light a 3 log 10 bacterial reduction (99.9%) was observed within 30 min while for TiN-Ag samples the same bacterial reduction was attained within ∼15 min. The absorption of the TiN-Ag samples in Kubelka-Munk (KM) units was directly proportional to the E. coli inactivation kinetics. TiN-Ag plasmon nanostructures are concurrently formed under low intensity visible light and accelerated bacterial inactivation. This study shows that TiN films have the potential to replace Ag-based disinfection materials leaching Ag into the environment.

“…In neurology, TiN-coated electrodes are used in chronically implanted devices for the treatment of spinal cord injury (Cogan, 2008). TiN-coating is also used in orthopedic implants, because of its excellent biological properties, such as the reduction of the release of cobalt-chromium-molybdenum ions, and the aesthetic appeal of the "golden color" (Mezger and Creugers, 1992;Wisbey et al, 1987).…”
