Characterization of Ti-C-N coatings deposited on Ti6Al4V for biomedical applications

Titanium and Titanium Alloys as Biomaterials

“…A recent tribological study carried out about the effect of deposition of Diamond-Like Carbon coatings on a substrate of Ti-6Al-4V for knee implants has confirmed that these types of coating improve the tribological response of substrate decreasing the coefficient of friction (µ) ( Table 1) and reducing the wear of the surface (Figure 8) [69]. For this study fretting tests were performed using alumina balls as counter body, bovine serum as lubricant and a continuous temperature of 37 ºC, trying to simulate real environment.…”

Advanced Surface Treatments on Titanium and Titanium Alloys Focused on Electrochemical and Physical Technologies for Biomedical Applications

“…Saenz de Viteri et al [148] studied the performance of Ti-C-N films deposited on Ti6Al4V alloy by cathodic arc evaporation technique. performance likely due to the higher sp 3 /sp 2 fraction which provides the necessary hardness (10 GPa) and the nanocrystalline graphite (nc-G) and amorphous carbon (a-C) structure that confers the lowest friction coefficient and best wear resistance to the coating.…”

CORR Insights®: Does Surface Topography Play a Role in Taper Damage in Head-neck Modular Junctions?

“…These approaches also would help us evaluate the changes made so far, and allow us to develop and propose modifications and innovations aimed at improving these systems. Use of other nonmetallic materials such as ceramics, surface treatments of metallic materials [4], and coatings [11], are promising methods to improve fretting and tribocorrosion performance of trunnion components. We must adopt a wellestablished lexicon that accurately describes fretting, corrosion, and wear of this mechanism, and a comprehensive, validated and more-objective classification of resultant damage than previous studies [6].…”
